(CNN) Sen. Elizabeth Warren officially launched her 2020 presidential campaign Saturday at a rally in Lawrence, Massachusetts, using the backdrop of Everett Mills -- the site of a historic 1912 labor strike led by women and immigrants -- to issue a call to action against wealthy power brokers who "have been waging class warfare against hardworking people for decades."

Over 44 minutes in sub-freezing temperatures, Warren described a political elite "bought off" and "bullied" by corporate giants, and a middle class squeezed so tight it "can barely breathe."

"The man in the White House is not the cause of what is broken, he is just the latest and most extreme symptom of what's gone wrong in America," Warren said of President Donald Trump. "A product of a rigged system that props up the rich and powerful and kicks dirt on everyone else. So once he's gone, we can't pretend that none of this ever happened."

The formal start of Warren's White House campaign comes as the Democratic primary intensifies by the day, with numerous candidates including Sens. Kamala Harris and Cory Booker already in the race, and others, like Sens. Bernie Sanders and Amy Klobuchar, expected to jump in soon. Trump's 2020 campaign manager welcomed Warren to the race with a statement predicting voters "will reject her dishonest campaign and socialist ideas like the Green New Deal."

In a warning to some of those rivals, Warren touted her refusal to accept donations from lobbyists, corporate PACs or the support of super PACs, and challenged "every other candidate who asks for your vote in this primary to say exactly the same thing."

Warren also unveiled a new, high-profile backer in Rep. Joseph P. Kennedy III, who introduced, endorsed and painted his former professor a prescient political voice.

"Before there was an editorial every day lamenting economic inequity, Elizabeth Warren knew that stock prices don't tell a full account of our country's economic story," Kennedy said. "Medical bankruptcies and foreclosures and paychecks are part of that story, too."

Kennedy led a Massachusetts delegation that included Sen. Ed Markey, Rep. Lori Trahan, Lawrence Mayor Dan Rivera and Boston City Councilor Michelle Wu -- all of them indicating their support for Warren's campaign.

"For six years, (Warren) has been fighting in the trenches for what is right," Markey said of his Senate colleague, calling her a "one woman protection detail fighting to ensure that Wall Street reforms stay on the books."

Warren was joined by family, including her husband, Bruce, two children and a gaggle of grandchildren.

Kennedy's decision to throw his support to his home state senator -- and not his good friend, former Rep. Beto O'Rourke, who is considering a bid of his own -- is a clear signal to fellow Democrats that she remains a serious primary contender despite a politically trying week.

In the days leading up to Saturday's announcement, Warren had been weighed down by new questions over her past claims to Native American heritage. The Washington Post reported that Warren wrote in 1986 that her race was "American Indian" in a Texas state bar registration card, adding to the list of instances in which the senator self-identified this way.

The disclosure prompted yet another public apology from Warren, just days after she had expressed remorse to Cherokee leaders for using a DNA test last year to try to show her Native American ancestry.

A Monmouth University poll showed Warren get a boost in national support after she announced her exploratory campaign at the end of last year. But it's not yet clear whether the controversy's revival on Wednesday will hurt her standing with voters.

Warren sought to turn the page on the controversy with Saturday's announcement and a six-state tour that began hours later.

After Lawrence, Warren travels north to campaign in New Hampshire before flying to Iowa -- her second visit to the Hawkeye State since announcing the formation of an exploratory campaign on New Year's Eve -- on Sunday and then South Carolina, Georgia, Nevada and California next week.

The campaign's decision to stage its first major rally in Lawrence, a former industrial mill town, was an appeal to the key constituency groups Warren hopes to appeal to -- including immigrants, women, working class families and union members.

"There'll be plenty of doubters and cowards and armchair critics this time around," Warren said. "But we learned a long time ago, you don't get what you don't fight for."

In 1912, textile workers in Lawrence, many of them immigrant women, walked off the job and went on strike to protest wage cuts. In an email to supporters last week, the campaign wrote: "Underpaid, overworked, and flat-out exploited workers from more than 50 countries gave Lawrence the nickname 'Immigrant City.'"

Warren has been fiercely critical of the Trump administration's immigration policy, particularly in light of the separation of migrant children from their families at the border.

"I think we need immigration laws that focus on people who pose a real threat and I don't think moms and babies are the place that we should be spending our resources. Separating a momma from a baby does not make this country safer," Warren said in an interview with CNN last summer, a message she has returned to during her time on the campaign trail.

Two weeks ago, Warren added more meat to her platform, which already includes a suite of anti-corruption proposals -- on Saturday she called it "a cancer on our democracy" -- introducing a new "wealth tax" on Americans with assets valued at $50 million or more.

The plan, according to documents provided by the campaign, would impose a 2% tax on Americans whose net worth exceeds $50 million. Billionaires would pay an additional 1%. Viewed alongside a new proposal from Sanders to hike the estate tax, Warren has positioned herself at the center of the progressive push to reduce corporate influence in Washington and economic inequality across the country.

In her speech, she pledged to go further, to "break up monopolies when they choke off competition" and "take on Wall Street banks so that the big banks can never again threaten the security of our economy."

"And when giant corporations -- and their leaders -- cheat their customers, stomp out their competitors, and rob their workers," Warren said, "let's prosecute 'em."

But even as Warren sharpens her policy positions and political message, the specter of additional, previously undisclosed examples of Warren labeling herself Native American on professional forms looms in the background. Warren did not address the potential for another distracting revelation when asked by reporters on Capitol Hill this week.

Another unanswered question: whether the dust-ups will permanently undermine Warren's campaign. Tribal activists, who were sharply critical over DNA test and earlier refusal to address the harm it might have done to their interests, have mostly welcomed her apologies.

And some Democrats in early voting states have seemed unfazed.

Collette Richard, an 18-year-old Des Moines resident and registered Democrat, reacted to the Washington Post story by saying she does not believe the issue should sway voters.

"I mean, your nationality or heritage shouldn't have anything to do with it, it should be your political views and where you stand as an American citizen -- that should pretty much lead you to make your decision," Richard said.

A candidate's ethnicity "doesn't matter," she added.

In Lawrence, the verdict was mostly mixed.

"That's actually one of the reasons why I'm not a huge supporter of her," John Boyle, an 18-year-old Democrat from Andover, said. "I don't love that. I don't think anyone does, so that definitely rubs me the wrong way."

Chrystal Pennisi, 40, who was born and works in Lawrence -- and said she was undecided but liked Warren -- was more forgiving.

"(Warren) was a kid and she was told this is your ancestry, just like any of us were. I don't think any of us really dug into who are parents and grandparents and so on said we were," Pennisi said. "It's not like she stole anything from anyone or she accepted any kind of special award because of it."</s>US Senator Elizabeth Warren, struggling to move past criticism over her claims of Native American heritage, aimed for a fresh start on Saturday with the formal launch of her 2020 presidential campaign, saying that she is fighting for all Americans.

The Massachusetts Democrat, a leader of the party's progressive wing, made her announcement from a historic site in Lawrence, northwest of Boston, that launched the US organized labor movement. Warren, 69, has made worker rights, fair wages and access to health care central to her campaign.

"This is the fight of our lives. The fight to build an America where dreams are possible, an America that works for everyone," Warren said. "And that is why I stand here today: to declare that I am a candidate for President of the United States of America."

Warren is part of an increasingly crowded and diverse field of Democrats vying for the chance to challenge President Donald Trump, the likely Republican nominee. A year before any ballots are cast in a Democratic primary, many of those candidates are spending this weekend talking to voters in the early-nominating states of Iowa, New Hampshire and South Carolina.

Warren's announcement will be followed on Sunday by U.S. Senator Amy Klobuchar, who has said she will reveal her presidential plans in her home state of Minnesota.

Warren picked up the endorsement of the Progressive Change Campaign Committee (PCCC) simultaneously with her launch - a group that could pump millions of dollars behind her candidacy and provide an outside attack dog against her Democratic opponents.

"We believe that Elizabeth Warren is the most electable Democrat and the best person to be president to defeat Trump," Adam Green, the co-founder of PCCC, said.

Warren's heritage claims have dogged her since her first campaign for the Senate in 2012, and Trump mockingly refers to her as "Pocahontas." Her ancestry drew fresh scrutiny earlier this week with the discovery that she described her race as American Indian on a form to join the Texas legal bar in the 1980s.

Warren has repeatedly apologized, saying the claim was based on "family lore" and she now understands tribal sovereignty dictates membership.

Trump's campaign described Warren as a "fraud." A statement from his campaign manager Brad Parscale said, "The American people will reject her dishonest campaign."

In addition to being a fierce Trump critic, Warren is an outspoken critic of Wall Street who gained national notoriety for her efforts to create the federal Consumer Financial Protection Bureau to regulate large banks.

Warren is one of four women so far seeking the Democratic nomination, an unprecedented number of female candidates vying to lead a country that has never had a woman chief executive.

Warren and the other women running so far, among whom are Senators Kamala Harris and Kirsten Gillibrand, are hoping to build on the success of women candidates who played a significant role in Democrats regaining control of the U.S. House of Representatives in November's congressional elections.

"I like her anger," said Christiane Alsop, who has donated to Warren's previous campaigns and is backing her presidential bid. "I like her fighting spirit."

Warren heads next to Iowa, where fellow Democratic contenders U.S. Senator Cory Booker and Pete Buttigieg, the mayor of South Bend, Indiana, campaigned on Friday.

"I am running for president right now because I believe Americans have surrendered to cynicism," Booker said at an event in Waterloo, Iowa. "I want to see a revival of civic grace."</s>LAWRENCE, MASS. -- Several Massachusetts lawmakers threw their support behind U.S. Sen. Elizabeth Warren’s White House run Saturday, arguing that she’s the best Democrat to take on incumbent President Donald Trump in 2020.

U.S. Sen. Ed Markey, D-Massachusetts, and U.S. Reps. Joe Kennedy III, D-Newton, and Lori Trahan, D-Westford, were among the state officials to take the stage to rally supporters who gathered in Lawrence for Warren’s 2020 campaign kickoff.

Elizabeth Warren officially joins 2020 presidential race, says she’s in the fight ‘all the way’

Markey said he was “honored” to help his U.S. Senate partner launch her White House run, offering that he has watched her fight for working class Americans throughout their time together in Congress.

“I’ve been in Congress for awhile now and no one, no one knows how to fight for what is right better than Elizabeth Warren," he said. "And these days, fighting for what is right means fighting the dangerous, divisive, hateful agenda of Donald Trump."

Markey, however, added that “no one know how to get under Donald Trump’s skin better than Elizabeth Warren.”

Pointing to her work on Wall Street regulations and as a member of the U.S. Senate, Kennedy argued that Warren is the one candidate in the 2020 race who has dedicated her life to fighting for working class Americans.

“I am here with you today because this country needs a leader who will restore the solidarity that Donald Trump stole. Who won’t cower from the big, tough battles, from the ugly injustice and oppression that still finds its way to American soil,” he said. “A leader will bring this country together to take on our greatest common threat: a system that protects the powerful and privileged while the rest struggle to scrape by. That leader is my colleague, my mentor, my friend: Elizabeth Warren."

Contending that the stakes of the 2020 election “could not be higher,” Trahan, meanwhile, said it’s critical the country selects a president who acknowledges that while the economy may work well for the wealthy, it’s not working for most Americans.

That type of champion, she said, “is someone like Elizabeth Warren.”

“Elizabeth will put her finger on the scale for working families --not banks, not multi-national corporations, and not those who can afford to give millions of dollars to political candidates,” she said.

Trahan further offered that Americans “could count on a President Warren to wake up each and every day and put the needs of the American people at the forefront of our policy debate and that real and enduring and significant change.”

“Elizabeth has proven time and again that she is up to the challenge and I am proud to be with her in this fight,” she said.

Warren formally launched her 2020 presidential campaign during a late-morning event outside the Everett Mill in Lawrence -- the site of the 1912 “Bread and Roses” labor strike.

The Massachusetts Democrat, who formed a presidential exploratory committee in late December, used the event to make her case to American voters and lay out her vision for a country that prioritizes working and middle-class people over the wealthy and well-connected.</s>(LAWRENCE, Mass.) — Democratic Sen. Elizabeth Warren made her bid for the presidency official on Saturday in this working-class city, grounding her 2020 campaign in a populist call to fight economic inequality and build “an America that works for everyone.”

Warren delivered a sharp call for change at her presidential kickoff, decrying a “middle-class squeeze” that has left Americans crunched with “too little accountability for the rich, too little opportunity for everyone else.” She and her backers hope that message can distinguish her in a crowded Democratic field and help her move past the controversy surrounding her past claims to Native American heritage.

Weaving specific policy prescriptions into her remarks, from Medicare for All to the elimination of Washington “lobbying as we know it,” Warren avoided taking direct jabs at President Donald Trump. She aimed for a broader institutional shift instead, urging supporters to choose “a government that makes different choices, choices that reflect our values.”

Warren announced her campaign in her home state of Massachusetts at a mill site where largely immigrant factory workers went on strike about 100 years ago, a fitting forum for the longtime consumer advocate to advance her platform.

She was scheduled to travel later in the day to New Hampshire, home to the nation’s first primary, where Warren could have an advantage as a neighboring-state resident with high name recognition. She intended to spend Sunday in Iowa, where the leadoff caucuses will be the first test of candidates’ viability.

Warren was the first high-profile Democrat to signal interest in running for the White House, forming an exploratory committee on New Year’s Eve.

She was introduced Saturday by Rep. Joe Kennedy III, D-Mass., who has endorsed her in the primary. The backing could prove valuable for Warren, given his status as a rising young Democratic star and his friendship with one of her potential 2020 rivals, former Rep. Beto O’Rourke, D-Texas.

Warren enters the race as one of the party’s most recognizable figures. She has spent the past decade in the national spotlight, first emerging as a consumer activist during the financial crisis. She later led the congressional panel that oversaw the 2008 financial industry bailout. After Republicans blocked her from running the Consumer Financial Protection Bureau, an agency she helped create, she ran for the Senate in 2012 and unseated a GOP incumbent.

She has $11 million left over from her commanding 2018 Senate re-election victory that can be used on her presidential run.

Still, Warren must compete against other popular Democrats who will be able to raise substantial money. A recent CNN poll found that fewer Democrats said they’d be very likely to support Warren if she runs than said the same of former Vice President Joe Biden or Sens. Kamala Harris of California and Bernie Sanders of Vermont. Still, about as many Democrats said they’d be at least somewhat likely to support Warren as said the same of Harris or Sanders.

That challenge is on display this weekend as Democratic presidential contenders — or those considering a run — fan out across the crucial early-voting states. New Jersey Sen. Cory Booker is in Iowa, while New York Sen. Kirsten Gillibrand is visiting South Carolina. Another possible presidential rival, Ohio Sen. Sherrod Brown, planned to be in New Hampshire on Saturday.

And Warren’s launch comes at a challenging moment for the 69-year-old senator. She’s apologized twice over the past two weeks for claiming Native American identity on multiple occasions early in her career. That claim has created fodder for Republicans and could overshadow her campaign.

The campaign launch will test whether the controversy is simply a Washington obsession or a substantive threat to her candidacy. Doug Rubin, a Boston-based strategist who advised Warren during her first Senate run in 2012, said in an interview that most voters will respond to “the powerful message she’s been talking about,” in terms of battling social and economic injustices, rather than the back-and-forth over her personal identity.

Another threat could come from a fellow senator who has yet to announce his own plans for 2020: Sanders. They’re both leaders of the Democrats’ liberal vanguard, but some Sanders supporters are still upset she didn’t support him during his 2016 primary run against Hillary Clinton. And as a senator from Vermont who won the New Hampshire primary, he would likely go into the Granite State as an early favorite if he decided to run again.

Despite their similarities, Warren and Sanders have taken somewhat divergent paths in recent months as they prepare for the primary. After proposing an “ultra-millionaire tax” that would hit the wealthiest 75,000 households in America, Warren told Bloomberg News last week that she continues to “believe in capitalism” but wants to see stricter rules to prevent gaming the system — a marked contrast with the self-described democratic socialism of Sanders.</s>LAWRENCE, MASS. – U.S. Sen. Elizabeth Warren officially launched her 2020 White House campaign Saturday, joining the growing field of Democratic candidates hoping to unseat incumbent Republican President Donald Trump.

Standing against the backdrop of Lawrence’s Everett Mills – the site of the “Bread and Roses” labor strike – the Massachusetts Democrat laid out her vision for an America that prioritizes working and middle-class people over the wealthy and well-connected.

Warren, who touted the labor law changes that came in wake of the historic 1912 strike, told supporters who gathered in freezing temperatures outside the mill that “the story of Lawrence is a story about how real change happens in America.”

“It’s a story about power – our power – when we fight together,” she said.

Arguing that the struggles mill workers faced 100 years ago are similar to those million of American families face today, Warren said she -- like the women of Lawrence -- is here to say “enough is enough" and take her fight for U.S. middle class workers to the White House.

“We are here to take on a fight that will shape our lives, our children’s lives and our grandchildren’s lives, just as surely as the fight that began in these streets more than a century ago. ... This is the fight of our lives. The fight to build an America where dreams are possible, an America that works for everyone. I am in that fight all the way,” she said. “And that is why I stand here today: to declare that I am a candidate for president of the United States of America.”

The senator laid out her campaign’s vision of “big, structural change,” which includes tackling wealth inequality, overhauling the criminal justice system, addressing climate change and rooting out corruption in Washington, among other things.

Warren, whose official entrance into the 2020 White House race came despite growing concerns raised about her viability as a candidate, acknowledged that her path to the White House will not be easy. She, however, offered that she’s up for the challenge.

“This won’t be easy. There are a lot of people out there with money and power and armies of lobbyists and lawyers. People who are prepared to spend more money than you and I could ever dream of, trying to stop us from making any of these solutions a reality,” she said. “People who will say it’s ‘extreme’ or ‘radical’ to demand an America where every family has some economic security and every kid has a real opportunity to succeed. I say to them, ‘Get ready, because change is coming faster than you think.’”

Warren faced renewed criticism this week over her controversial Native American heritage claims after the Washington Post reported that she listed her race as “American Indian” on a Texas State Bar registration card in 1986.

The report, which marked the first instance yet of Warren making the assertion in her own handwriting, prompted new apologies from the senator.

Warren reached out to Cherokee Nation leaders earlier this month to express regret over her decision to release DNA test results backing up her ancestry claims along with a video highlighting her “family story" in October.

Republican National Committee spokesman Michael Ahrens, however, argued that the senator’s actions were too little, too late.

“We’ve always known that Elizabeth Warren’s socialist policies were far outside the mainstream. But Warren’s disastrous handling of her false minority claims and her refusal to apologize until now has everyone, including her own supporters, cringing at her campaign," he said in a statement.

Despite such criticism, several Massachusetts lawmakers joined Warren for her Lawrence 2020 campaign launch, including U.S. Reps. Joe Kennedy III, D-Newtown; and Lori Trahan, D-Westford; U.S. Sen. Ed Markey, D-Massachusetts; Boston City Councilor Michelle Wu; Suffolk County Sheriff Steve Thompkins; and Lawrence Mayor Dan Rivera.

Many Massachusetts residents who turned out for the campaign kickoff, meanwhile, said they’d rather see the 2020 race focus on issues that matter to many Americans, such as income inequality, student debt and health care -- not Warren’s heritage.

Tracey Peters, an Andover resident who attended the Lawrence event, said she’d like to better understand why the senator has drawn criticism for speaking her mind. She praised Warren for bringing attention to things like student debt and for standing up to the banking industry.

"All she’s doing is trying to protect us when the story’s twisted and, of course as usual, it’s gets pushed on things like ‘Oh, she said she’s Native American.’ Like, who cares about that?” she said. “Look at what she’s done -- what she’s really done. I think the story needs to come back to more of that, which is difficult in this day and age.”

Ben Callahan, of Groveland, agreed that he doesn’t believe Warren’s ancestry should matter “entirely.”

“I didn’t get why people felt like it was such a big deal. I kind of just brushed it off. It wasn’t my top concern,” he said.

Callahan, who noted that he’s looking at other progressive candidates, said he’d like to see White House hopefuls make gun control, student loans, income inequality and LGBTQ issues top priorities in 2020.

Bridget Rawding, of Lawrence, said she’s “interested about what people are going to do about the issues that matter in this country.”

“I’m not particularly paying attention to the noise and the distractions of any candidate, whether it’s someone I support or not,” she said. “I think that’s easy to kind of get full of outrage about that, but it doesn’t fix anything. I want to know what people are going to do to fix the issues that matters that we face.”

Rawding added that she’s thrilled Warren chose Lawrence to launch her 2020 Democratic presidential run, particularly in wake of the deadly September gas explosions that impacted the city and surrounding communities.

“Through the gas crisis she has been very supportive and fought for congressional hearings and everything. I think, we’re a pretty resilient city and it’s nice to see something like this so soon after what could’ve been an even worse disaster than it was,” she said.

Warren’s Lawrence event came just over a month after she announced her presidential exploratory committee, ending years’ of speculation as to whether she would seek a 2020 White House run.

Ahead of the 2016 election, Democracy for America and MoveOn.org Political Action launched the “Run Warren Run” campaign to push the senator to enter the presidential race. Although the Democrat decided against such a run, rumors about her White House ambitions continued to swirl as Warren gained national attention for her vocal criticism of Trump and other GOP leaders.

That speculation hit a fever pitch just months ahead of her U.S. Senate re-election, when the Democrat told supporters at a Holyoke town hall that she would consider running for president after the 2018 midterms.

Elizabeth Warren tells New Hampshire voters it’s time to ‘dream big,’ ensure country works for all Americans

Since launching her exploratory committee, Warren has traveled to Iowa, New Hampshire, South Carolina and Puerto Rico to meet with voters and test out her 2020 message.

Immediately following her Lawrence announcement, the senator embarked on a seven-state organizing tour to drum up support for her campaign in New Hampshire, Iowa, South Carolina, Georgia, Nevada and California -- must-win early primary states.

Elizabeth Warren to visit New Hampshire, 6 other early primary states after Lawrence announcement</s>Massachusetts Sen. Elizabeth Warren formally kicked off her 2020 presidential campaign on Feb. 9 . Here's a look at Warren's background:Warren was born in Oklahoma and attended the University of Houston and Rutgers School of Law. She initially had a career in academia, teaching at Rutgers, the University of Texas, the University of Pennsylvania and Harvard.She emerged as a national political figure in the aftermath of the 2008 financial crisis, chairing the Congressional Oversight Panel for the Troubled Asset Relief Program. She quickly became one of the party's more prominent liberals even as she sometimes fought with Obama administration officials over their response to the market turmoil.Warren then worked with the Obama administration to establish the Consumer Financial Protection Bureau.Warren won a Senate seat in 2012, becoming Massachusetts' first female senator. She was re-elected in 2018 before launching her exploratory committee.Should she launch a campaign, Warren must move past a widely panned October release of a DNA test meant to bolster her claim to Native American heritage. The move was intended to rebut Trump's taunts of Warren as "Pocahontas." Instead, her use of a genetic test to prove ethnicity spurred controversy that seemed to blunt any argument she sought to make.Warren's campaign is likely to revolve around the same theme she's woven into speeches and policy proposals in recent years: battling special interests, paying mind to the nexus between racial and economic inequities. She has $11 million left over from her commanding 2018 Senate re-election victory that can be used on her presidential run.One of her most significant competitors could be Sen. Bernie Sanders, a Vermont independent who is eyeing another presidential run harnessing the same populist rhetoric.</s>Presidential campaign season is not yet in full swing, but Democratic candidates are already taking swings at the president. On Sunday, Massachusetts Senator and 2020 contender Elizabeth Warren suggested Trump's 2020 campaign might not be an issue in the long run because, as she suggested, she's not sure it will even last that long.

“By the time we get to 2020, Donald Trump may not be president,” Warren told a voters at a Cedar Rapids, Iowa event, according to The Washington Post. “In fact, he may not even be a free person.”

Warren appeared to be referencing the ongoing investigations into Trump's administration, including both the Russia probe and those inquiries currently being led by committees within Congress. To be clear, Trump has not been accused of any crimes and has denied any wrongdoing. But the tensions between Warren and the president exceed any congressional investigations into Trump's business dealings or his 2016 bid for the presidency.

Specifically, Warren's remark comes one day after Trump's most recent jab at her family ancestry. The president has long cast doubt on whether or not the Senator is truly a descendant of Native Americans, as she has long said, and he doubled down on that skepticism on Saturday, the day Warren formally announced her campaign.

"Today Elizabeth Warren, sometimes referred to by me as Pocahontas, joined the race for President," Trump tweeted. "Will she run as our first Native American presidential candidate, or has she decided that after 32 years, this is not playing so well anymore? See you on the campaign TRAIL, Liz!"

Since stepping into the political arena, Trump has dubbed Warren with the nickname "Pocahontas," which many have criticized as a racist slur. On Saturday, he appeared to be using the topic to taunt Warren, while also musing about whether her claim to Native American ancestry has done her more harm than good.

CEDAR RAPIDS, Iowa (AP) — The Latest on Democratic presidential candidate Elizabeth Warren, who is campaigning in Iowa (all times local):

Democrat Elizabeth Warren says President Donald Trump "may not even be a free person" by next year's election.

The Massachusetts senator's comments came Sunday as the Democratic presidential candidate campaigned in Iowa a day after Trump renewed his criticism of her past claims of Native American heritage. In a tweet, Trump called Warren "Pocahontas" and said he would see her "on the campaign TRAIL."

The White House didn't explain what the president was referring to in his tweet, though some Democrats accused him of making light of the Trail of Tears — the forced removal of Cherokee and several other Native American tribes from their lands in the 1830s. Warren's campaign wouldn't say what the senator believes Trump was referencing.

Warren has largely avoided talking about Trump since she began testing the waters for a campaign more than a month ago.

Sen. Elizabeth Warren is returning to South Carolina this week as part of a tour of early voting states following the official launch of her 2020 presidential campaign.

Warren's campaign says the Massachusetts Democrat will make her first trip to Greenville on Saturday for an organizing event. She did something similar last month in the state capitol of Columbia.

Warren's South Carolina swing overlaps with Democratic Sen. Kamala Harris of California, who is also eyeing the White House. Harris will be in the state on Friday and Saturday.

Warren officially announced her candidacy Saturday in Lawrence, Massachusetts, and is visiting New Hampshire and Iowa this weekend.

In addition to South Carolina, she is also making stops in Georgia, Nevada and California.
