Authorities said they recovered a cell phone, a laptop computer and other electronic devices from the suspect.</s>The total number of bomb-like devices reached 12 Friday after two more suspicious packages were recovered, one in Florida addressed to New Jersey Sen. Cory Booker and the other in New York addressed to former Director of National Intelligence James Clapper.

One person is in custody, and more details are expected at a 2:30 press conference, according to a spokesperson for the Justice Department.

A source told USA TODAY a package addressed to Clapper was recovered at a Manhattan postal facility. Like some of the previous packages addressed to prominent Democrats, the one found in New York City on Friday had the office of Florida Democratic Rep. Debbie Wasserman Schultz as the return address, a photo obtained by CBS News showed.

The nation has been on heightened alert in the wake of bomb-like devices addressed to top liberals, including former President Barack Obama, former Secretary of State Hillary Clinton and former Vice President Joe Biden.

The New York Police Department on Friday closed a Manhattan intersection to traffic and pedestrians as investigators handle the suspicious package. The NYPD said pedestrians and motorists should avoid the area near W. 52nd Street between 8th and 9th Avenues as police investigated the area.

The device addressed to Booker was recovered at a mail sorting distribution center in Opa Locka, Fla., which has drawn intense investigative interest in recent days, as authorities believe that many of the suspected explosive devices passed through the state, a law enforcement official said.

Investigators are continuing to review mail streams in and out of Florida, attempting to pinpoint locations where the parcels may have originated, said the official who is not authorized to comment publicly.

Sen. Booker, a likely presidential contender in 2020, had no public events scheduled Friday. When contacted for comment, his office directed calls to law enforcement, citing the ongoing investigation.

On Wednesday, after news of the initial wave of packages broke, Booker, 49, tweeted: "These targeted acts of terror are despicable cowardice."

Attorney General Jeff Sessions cancelled a planned trip to Louisville, Ky., Friday to ensure that all federal law enforcement resources, including the aircraft and personnel required for the attorney general's travel, were being devoted to the investigation.

Sessions was scheduled to speak in Louisville about the federal government's efforts to combat the opioid crisis.

Police have investigated multiple unattended packages in recent days and are urging the public to report anything that could be dangerous.

On Thursday, the NYPD Bomb Squad handled multiple unattended packages inside a mall at 10 Columbus Circle before declaring the area safe. Police urged the public to "say something if you see something," in a tweet.

New York Police Department Commissioner James O’Neill said in a news conference earlier Thursday that the devices were not being treated as a hoax, describing them as "suspected explosive devices."

The powder found in packaging in New York addressed to CNN's offices wasn’t a biological weapon, but further testing was being done, O’Neill said. The devices were being examined at the FBI lab in Quantico, Virginia.

FBI Assistant Director Bill Sweeney on Thursday said the investigation is nationwide and noted that more devices could be discovered. “It does remain possible that further packages have been or could be mailed," he said. "These devices should be considered dangerous.”

Kevin Barry, a former member of New York Police Department's bomb squad and a former director of the International Association of Bomb Technicians and Investigators, expected the FBI analyses to be focused on both the design and recovery of physical evidence.

Testing would gauge the functionality of the devices, check the type of pipe used and examine the powder to determine whether it is high explosive, low explosive or a chemical substance intended to be dispersed when the devices were triggered, Barry said.

A look at those who were addressed packages that carried suspicious devices in October 2018, as of Oct. 25.</s>Authorities have arrested a man named Cesar Sayoc in connection to the suspicious packages believed to be explosive that were sent to CNN and politicians across the country, according to The New York Times.

The arrest, which was made in Florida, comes after a 12th package addressed to James Clapper (former director of National Intelligence) was discovered this morning (October 26). He joined the list with the Obamas, the Clintons, Eric Holder, Cory Booker, New York Governor Andrew Cuomo, Maxine Waters and more.

Cesar is a registered republican who was born in New York and has a long criminal history ranging from felony theft to fraud. He also a known Trump supporter.

Explosive devices targeting U.S. Senator Kamala Harris and billionaire Democratic activist Tom Steyer were intercepted Friday in what authorities called a Florida man’s plot to mail more than a dozen pipe bombs to politicians and public figures critical of President Trump.

An improvised explosive device, or IED, sent in a package addressed to Harris was discovered by a post office worker in Sacramento, according to the FBI. A second bomb in a package addressed to Steyer was found at a mail processing facility at 1625 Rollins Rd. in Burlingame.

The packages were discovered on the same day a nationwide manhunt ended with the arrest of Cesar Sayoc, 56, who was taken into custody in Plantation, Fla. His fingerprints and DNA were allegedly found on another bomb mailed to Rep. Maxine Waters, D-Los Angeles.

At least 13 packages containing pipe bombs were sent to Democratic Party leaders including former President Barack Obama, former Vice President Joe Biden and Trump’s 2016 election opponent, Hillary Clinton, authorities said.

Postal service workers in Burlingame were escorted out of the Rollins Road facility after the device was discovered. Agents continued investigating the scene Friday afternoon.

The device was taken off-site, according to Burlingame police. FBI officials in San Francisco tweeted that the package was “rendered safe” around 1 p.m.

Mail carrier Cynthia Maffei said she was about to leave the facility around 10 a.m. when the package sent to Steyer was found by another employee. Thirty minutes later, Maffei said, the post office was evacuated.

“They were seriously telling us to get out now,” she said. “It makes me nervous.”

Supervisors told her to “forget everything,” get out of the building and not come back for the day, Maffei said.

Steyer ran the hedge fund Farallon Capital for 26 years and has donated $65 million to Democratic candidates and environmental causes during the 2016 elections, according to Forbes. He has also led an effort to have Trump impeached.

At a youth summit Friday, Trump said he was “pleased” with the arrest of Sayoc, but many Democratic leaders blamed the president’s rhetoric for creating a dangerous political climate.

Lily Adams, a spokeswoman in Harris’ office, said it was time for “leaders across the political spectrum to take seriously the power they hold,” adding that elected officials should “elevate our discourse and bring people together.”

Steyer tweeted out a statement calling on the Republican Party to denounce any attacks “on the rights and dignity of any American.”

“We are seeing a systematic attack on our democracy and our rule of law that extends much further than just one isolated terrorist in Florida,” Steyer wrote. “Whether it’s voter suppression, voter intimidation, attacks on our free press, gerrymandering, or attempted violence — the trust and norms that are the actual basis of our civil society and political system are being eroded.”

In total, 13 IEDs consisting of six inches of PVC pipe, a small clock, battery, wiring and energetic material have been found, according to the criminal complaint against Sayoc. FBI Director Christopher Wray warned that more packages could be found in the coming days.

Authorities declined to comment on the motive behind the bombs, though Sayoc, who has a long arrest record, had expressed contempt for liberals and reverence for Trump, including on social media. In Florida, authorities seized Sayoc’s white van, which was adorned with pictures of Trump and stickers critical of Democratic leaders and news network CNN, another of the alleged bomber’s targets.

Rep. Jackie Speier, D-Hillsborough, told The Chronicle that Sayoc’s targets are people on “the president’s enemies list.”

Trump “has gone out of his way to throw verbal bombs,” Speier said. “He elevates people who do violent things. This could have been catastrophic to our country.”

Attorney General Jeff Sessions said he “didn’t know” why Democrats were targeted.

Sayoc was charged with five federal crimes that included transporting explosives across state lines, illegally mailing explosives, threatening former presidents and other people, threatening interstate communications, and assaulting assaulting federal officers, according to the criminal complaint.

He could face up to 48 years in prison if convicted, Sessions said.

Prior to the announcement of the arrest, Trump was criticized for bashing CNN in a Friday morning tweet that used quotation marks around the word “bomb.”

After 12 potential explosive devices were mailed to prominent Democrats, law enforcement authorities Friday continue to search post offices after warning the public that more packages could still be at large.

"This has to be taken with the most seriousness," New York City Police Commissioner James P. O’Neill told reporters at a Thursday news conference when asked to address claims that the mailings were part of a hoax. "We are treating them as suspected explosive devices."

So far, none of the suspected packages have injured anyone.

Officials were searching a mail distribution center in Florida Thursday night for possible clues on where the packages originated. A scare at Time Warner Center in New York also caused more panic, after reports of unattended packages.

Here's what we know now.

What do we know about the latest packages?

The two latest packages bring the total to 12 bomb-like devices.

The FBI confirmed Friday that they had found a suspicious package "similar in appearance to the others" that was addressed to Democrat Sen. Cory Booker in Florida.

Former Director of National Intelligence James Clapper was the target of another bomb-like device recovered in Manhattan, a person familiar with the matter told USA TODAY Friday. The device was addressed to Clapper and had the office of Florida Democratic Rep. Debbie Wasserman Schultz as the return address.

The New York Police Department had closed a Manhattan intersection to traffic and pedestrians near W. 52nd Street between 8th and 9th Avenues on Friday morning to handle the suspicious package.

The person was not authorized to speak about the matter publicly.

A postal distribution center in Opa Locka, Florida, is being closely monitored because several of the suspicious packages might have passed through it, according to a law enforcement official who is not authorized to comment publicly. Miami-Dade police bomb-squad and K-9 officers were called out to the center Thursday evening as federal authorities continued their investigation at the facility.

Time Warner Center in midtown Manhattan, where CNN's New York offices are located, was partially evacuated Thursday night when the New York Police Department responded to reports of a pair of unattended packages.

The packages were cleared and no threat was found. Earlier this week, a bomb-like device was sent to the building addressed to former CIA Director John Brennan and the CNN offices were evacuated.

Will there be more suspicious packages?

Authorities warned the public on Thursday to be on the lookout for more suspicious packages that could still be in the mail system.

O'Neill told reporters there are no current or credible threats that law enforcement is aware of. And he expressed confidence that the culprit would be caught.

Two law enforcement officials said Thursday that investigators have been increasingly focused on the mail streams in and out of Florida, largely since the device addressed to Holder was recovered when it was re-routed back to the return address of Wasserman Schultz. The two officials who are not authorized to comment publicly said authorities had not identified a suspect.

More: White House denies that Trump's rhetoric to blame for suspicious packages, 'anger' in society</s>Suspicious packages addressed to New Jersey Sen. Cory Booker and former National Intelligence Director James Clapper - and similar in appearance to pipe bomb devices sent to other prominent Democrats - have been intercepted, the FBI said Friday, as investigators scrambled from coast to coast to locate the culprit and motives behind a bizarre plot aimed at critics of President Donald Trump.The discoveries brought to 12 the total number of devices addressed in recent days to Democratic figures including former President Barack Obama, former Vice President Joe Biden and Hillary Clinton.The FBI said the package to Booker was intercepted in Florida. The one discovered at a Manhattan postal facility was addressed to Clapper c/o CNN. An earlier package had been sent to former Obama CIA Director John Brennan in care of CNN in New York.Investigators were analyzing the innards of the crude devices to reveal whether they were intended to detonate or simply sow fear just before Election Day.Law enforcement officials told The Associated Press that the devices, containing timers and batteries, were not rigged like booby-trapped package bombs that would explode upon opening. But they were uncertain whether the devices were poorly designed or never intended to cause physical harm. A search of a postal database suggested at least some may have been mailed from Florida, one official said. Investigators are homing in on a postal facility in Opa-locka, Florida, where they believe some of the packages originated, another official said.The officials spoke on condition of anonymity because they were not authorized to discuss the ongoing investigation by name.Homeland Security Secretary Kirstjen Nielsen, in an interview Thursday night with Fox News Channel, acknowledged that some of packages originated in Florida.New details about the devices came as the four-day mail bomb scare spread nationwide, drawing investigators from dozens of federal, state and local agencies in the effort to identify one or more perpetrators.The targets have included Obama, Hillary Clinton, CNN and Rep. Maxine Waters of California. The common thread among them was obvious: their critical words for Trump and his frequent, harsher criticism in return.Trump claimed on Friday he was being blamed for the mail bombs addressed to his critics, complaining in a tweet sent before dawn: "Funny how lowly rated CNN, and others, can criticize me at will, even blaming me for the current spate of Bombs and ridiculously comparing this to September 11th and the Oklahoma City bombing, yet when I criticize them they go wild and scream, 'it's just not Presidential!'"At a press conference Thursday, officials in New York would not discuss possible motives or details on how the packages found their way into the U.S. postal system. Nor would they say why none of the packages had detonated, but they stressed they were still treating them as "live devices.""As far as a hoax device, we're not treating it that way," police Commissioner James O'Neill said.Details suggested a pattern - that the items were packaged in manila envelopes, addressed to prominent Trump critics and carried U.S. postage stamps. The devices were being examined by technicians at the FBI's forensic lab in Quantico, Virginia.The packages stoked nationwide tensions and fears as voters prepared to vote Nov. 6 to determine partisan control of Congress - a campaign both major political parties have described in near-apocalyptic terms. Even with the sender still unknown, politicians from both parties used the threats to decry a toxic political climate and lay blame."A very big part of the Anger we see today in our society is caused by the purposely false and inaccurate reporting of the Mainstream Media that I refer to as Fake News," Trump said on Twitter. "It has gotten so bad and hateful that it is beyond description. Mainstream Media must clean up its act, FAST!"Former CIA Director Brennan, the target of a package sent to CNN, fired back."Stop blaming others. Look in the mirror," Brennan tweeted. "Your inflammatory rhetoric, insults, lies, & encouragement of physical violence are disgraceful. Clean up your act....try to act Presidential."CNN didn't immediately respond to messages seeking comment before business hours Friday.The list of bombing targets spread from New York, Delaware and Washington, D.C., to Florida and California.The explosive devices were packed in envelopes with bubble-wrap interiors bearing six American flag stamps and the return address of Florida Rep. Debbie Wasserman Schultz, the former chairwoman of the Democratic National Committee.The bombs seized Wednesday were about 6 inches (15 centimeters) long and packed with powder and broken glass, according to a law enforcement official who viewed X-ray images. The official said the devices were made from PVC pipe and covered with black tape. At the New York briefing, authorities confirmed that at least some of the packages were distributed through the U.S. mail, and cautioned that there could be additional devices in the postal system. They said investigators searching for more suspicious parcels had not found any during the previous eight hours.David Chipman, a retired federal ATF agent and now senior policy adviser for the Giffords Center, said the details revealed telltale signs that could help guide investigators.The tape on the pipe is "an investigator's dream," he said, recalling a case in Texas that was solved because the fibers on the tape were traced to the bomber's dog. He said bombers tend to plot methodically."This is someone sitting down and spending time thinking about what they're going to do to someone else. And some people like to relish that," he said.The new packages discovered Thursday set off a new wave of alarm.A retired New York police detective working in security in De Niro's Manhattan office called police after seeing images of a package bomb sent to CNN and recalling a similar package addressed to the actor, officials said.The packages addressed to Biden were intercepted at Delaware mail facilities in New Castle and Wilmington, according to a law enforcement official who, like others, wasn't authorized to discuss the investigation and spoke on condition of anonymity.Like earlier targets, both Biden and De Niro have been sharply critical of Trump. The actor dropped an expletive insult at Trump at this year's Tony Awards and apologized to Canadians for the "idiotic behavior of my president." Biden said last week that the president may not "know what he's doing" and coddles dictators.Trump has called Biden "Crazy Joe" and "mentally weak."On Thursday, during a campaign trip to suburban Buffalo, Biden said: "We've got to get off this hate machine. We've got to come together."The packages were "clearly an effort to terrorize people politically, to choose people for political purposes and attack them because of their beliefs," New York Mayor Bill de Blasio said.The first crude bomb to be discovered was delivered Monday to the suburban New York compound of George Soros, a liberal billionaire and major contributor to Democratic causes. Soros has called Trump's presidency "dangerous."Similar packages addressed to Clinton and Obama were intercepted on their way to Clinton's New York home, where she lives with former President Bill Clinton, and to Washington, where Obama lives with his wife, Michelle Obama. The Secret Service said neither package reached its intended recipient.Other packages were sent to frequent Trump critics Waters, D-Calif., and former Obama Attorney General Eric Holder. His ended up at the Sunrise, Florida, office of Wasserman Schultz, who was listed as the return address.A police bomb squad removed the package addressed to Brennan on Wednesday from CNN's New York office, which was evacuated.In response to the events, Trump decried political violence but also joked about moving to more polite speeches."Let's get along," he said at a Wisconsin rally Wednesday night. "By the way, do you see how nice I'm behaving tonight? Have you ever seen this?"</s>Postal service police screen employees entering the Royal Palm processing and Distribution Center, Oct. 25, 2018 in Opa-locka, Fla.

Here's what we know now.

One taken into custody

Cesar Sayoc, 56, has been charged in Florida. Sayoc has a prior criminal history, including a 2002 charge for threatening to "throw, project, place or discharge any destructive device." His criminal record dates back to 1991, with arrests for theft, drug offenses and traffic infractions.

Sayoc was charged with five federal crimes Friday, including interstate transportation of an explosive, illegal mailing of an explosive and threats against former presidents. He faces a maximum of 48 years in prison, Attorney General Jeff Sessions said in a news conference Friday.

Sayoc, of Aventura, Florida, is a registered Republican and last voted in the November 2016 election. He graduated from North Miami Beach High School in 1980.

Authorities used a fingerprint found on an envelope sent to Rep. Maxine Waters to identify Sayoc as a suspect, FBI Director Christopher Wray said Friday.

In this undated photo released by the Broward County Sheriff's office, Cesar Sayoc is seen in a booking photo in Miami.

(Broward County Sheriff's Office via AP)

President Donald Trump lauded law enforcement officials for the arrest on Friday during the Young Black Leadership Summit at the White House. He called the bombings "despicable" and said political violence has "no place in our country."

Trump's comments come after tweets this morning alleging the bomb-like devices were shifting the national conversation away from early voting for the Nov. 6 midterm elections.

What do we know about the latest packages?

The three latest packages bring the total to 14 bomb-like devices.

The FBI confirmed Friday that they had found a suspicious package "similar in appearance to the others" that was addressed to Democrat Sen. Cory Booker in Florida. A suspicious package was also recovered at Sen. Kamala Harris's office in Sacramento, California Friday. Another package was intercepted at a mail facility in Burlingame, California addressed to billionaire Tom Steyer.

NBC News said he will face charges in connection with pipe bomb packages that were mailed across the US.

DNA evidence was involved in the identification and arrest of Sayoc, NBC News reports.

The Associated Press reports Justice Department spokeswoman Sarah Isgur Flores said authorities planned to announce more information at a press conference.

Earlier Friday, authorities said suspicious packages addressed to New Jersey Sen. Cory Booker and former National Intelligence Director James Clapper -- both similar to those containing pipe bombs sent to other prominent critics of President Donald Trump -- had been intercepted.

Twelve such discoveries have been made so far. Officials have been working to find a culprit and possible motive while it's unclear if new packages were being sent or simply surfacing after a period in mail system.</s>Federal authorities have arrested one individual in connection with suspected explosives sent to top Democrats, former senior US officials and prominent critics of President Donald Trump, the Department of Justice said on Friday.

The news of the arrest came not long after authorities said two more suspicious packages were found on Friday, bringing the total number of suspect packages discovered over the past week to 12.

The name and location of the individual were not immediately disclosed, but officials are expected to provide additional details at a news conference later in the day.

The two new packages discovered on Friday were addressed to US Senator Cory Booker and James Clapper, the former US director of national intelligence.

There were also reports that a possible second package addressed to Clapper was discovered at a US mail facility in New York. Those reports have not been confirmed.

"This is definitely domestic terrorism, no question about it in my mind," Clapper told CNN. "This is not going to silence the administration's critics."

Prior to the arrest, Attorney General Jeff Sessions said on Friday that the Justice Department was dedicating every available resource to the investigation and "I can tell you this: We will find the person or persons responsible. We will bring them to justice."

In Florida, where the investigation was focused, local police and canine units joined federal investigators on Thursday to examine a sprawling US mail distribution centre at Opa-Locka, northwest of Miami.

US Homeland Security Secretary Kirstjen Nielsen said Florida appeared to be the starting point for at least some of the bomb shipments.

"I am confident that this person or people will be brought to justice," Nielsen told Fox News Channel on Thursday.

The wave of parcel bombs has been denounced by authorities as terrorism and comes less than two weeks before US congressional elections. The results could alter the balance of power in Washington, DC.

Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, told MSNBC on Friday that the mail bombs were stoking fear across the county and that US leaders, including Trump, must reassure the public.

"Elected officials and others need to say that this is not who we are as a country," Warner said. "That would be a heck of a lot stronger if that message also came from the White House."

All the individuals targeted by the suspicious packages have often been maligned by right-wing critics. They included Democratic Party donor George Soros, former President Barack Obama, former Vice President Joe Biden, and former Secretary of State and presidential candidate Hillary Clinton.

The FBI said that at least five of the packages bore a return address from the Florida office of US Representative Debbie Wasserman Schultz, a former chair of the Democratic National Committee.

There has been an outcry from Trump's critics, who charged that his inflammatory rhetoric against Democrats and the press has created a climate for politically motivated violence.

After first calling for "unity" and civil discourse on Wednesday, Trump lashed out again Thursday at the "hateful" media. His supporters accused Democrats of unfairly suggesting the president was to blame for the bomb scare.

"Funny how lowly rated CNN, and others, can criticize me at will, even blaming me for the current spate of Bombs and ridiculously comparing this to September 11th and the Oklahoma City bombing, yet when I criticize them they go wild and scream, "it's just not Presidential!" Trump said on Twitter early on Friday.

Later on Friday morning, he tweeted that "this 'bomb' stuff" is slowing the momentum for Republicans in the leadup to the November 6 midterm elections.

"Republicans are doing so well early voting, and at the polls, and now this 'bomb' stuff happens and the momentum greatly slows - news not talking politics," he said, adding "Very unfortunate, what is going on. Republicans go out and vote!"

Authorities believe the packages, which were intercepted before reaching their intended recipients, all went through the US Postal Service at some point, news agencies reported, citing federal security sources. None detonated and no one has been hurt.

The devices were thought to have been fashioned from bomb-making designs widely available on the internet, a federal law enforcement source told Reuters news agency.

Still, investigators are treating the devices as "live" explosives, not a hoax, said James O'Neill, the New York City police commissioner.

Investigators have declined to say whether the devices were built to be functional. Bomb experts and security analysts say that based on their rudimentary construction it appeared they were more likely designed to sow fear than to kill.

The parcels each consisted of a manila envelope with a bubble-wrap interior containing "potentially destructive devices," the FBI said. Each was affixed with a computer-printed address label and six US "Forever" postage stamps, the agency said.

Two packages were sent to Waters and Biden. Others who received the bombs were former Attorney General Eric Holder, former CIA director John Brennan, US Representative Maxine Waters of California, and actor Robert De Niro.

"I thank God no one's been hurt, and I thank the brave and resourceful security and law enforcement people for protecting us," De Niro said in a statement. "There's something more powerful than bombs, and that's your vote. People MUST vote!"
Authorities are also investigating a packages addressed to former Director of National Intelligence James Clapper and billionaire Tom Steyer.
