 President Donald Trump on Wednesday said he would move to fortify U.S. borders “even more” in the wake of an attack in France that left three dead and more than a dozen wounded, criticizing Democratic congressional leaders for pushing back on his requests for money to build a proposed border wall with Mexico. 
 
 “Another very bad terror attack in France. We are going to strengthen our borders even more,” he wrote in a tweet, without elaborating on his plans. “Chuck and Nancy must give us the votes to get additional Border Security!”

 A gunman opened fire Tuesday at an outdoor Christmas market in Strasbourg, France, near the border with Germany. Although he has not been apprehended, the Strasbourg-born gunman was known to authorities before the shooting, which French officials have said is “probably” terrorism-related. 
 
 Trump met Tuesday with Senate Minority Leader Chuck Schumer and House Minority Leader Nancy Pelosi over his $5 billion request for funding to build the border wall, a sit-down that quickly deteriorated into a partisan brawl on live television, culminating with Trump’s declaration that he would be “proud” to force a partial government shutdown if his demands were not met.

 While lawmakers in the Senate have agreed to a bipartisan deal that would provide $1.6 billion for border security, none of those taxpayer dollars would be allowed to fund a wall, but only fencing and other resources. Trump has upped his request to $5 billion for his long-promised wall and is not backing down, boasting Tuesday that “I don’t mind owning that issue.” 
 
 Though the legislative and executive branches of the government are under Republican control, any spending bill will need 60 votes in the Senate, meaning some Democratic support is required. 
 
 Schumer and Pelosi said Tuesday they had pitched the president either a yearlong stopgap for the Department of Homeland Security, freezing its funding at current levels, or a yearlong continuing resolution for the remaining spending bills Congress has yet to consider. Either option would deny Trump a proposed $300 million boost for border security but would keep the government open as negotiations continued. 
 
 Trump also sought to tie his demands for border security to the Obama administration’s Iran nuclear deal, a pact his administration withdrew from earlier this year, falsely claiming in another tweet that “the Democrats and President Obama gave Iran 150 Billion Dollars and got nothing, but they can’t give 5 Billion Dollars for National Security and a Wall?” 
 
 The president appears to refer to dubious claims by opponents of the deal that lifting sanctions on Iran in exchange for curbing its nuclear weapons programs freed up $150 billion in frozen assets for the country, a far cry from the $56 billion estimated by then-Treasury Secretary Jack Lew and the $25 billion to $50 billion estimated by some experts. That money is in a separate category because it never belonged to U.S. taxpayers, unlike border wall funding appropriated by Congress. ||||| Sen.

 Chuck Schumer is taking his big spending boost for Donald Trump’s border wall off the table. 
 
 The Senate minority leader, through an aide, informed the White House that he was retracting the offer he made last week to give Trump well north of the $1.6 billion in wall funding Trump had asked for this year, according to two Democrats. And now they say Trump will simply not get a better deal than that on his signature campaign promise.

 Schumer “took it off,” said Illinois Sen. Dick Durbin, the No. 2 Senate Democrat. “He called the White House yesterday and said it’s over.” 
 
 After the publication of this story, a spokesman clarified that the wall offer was retracted Sunday, rather than Monday. Schumer told reporters that he withdrew his suggestion, offered midday Friday, because it was meant to be part of a broader package that would have averted a government shutdown.

 "The thought was that we could come to an agreement that afternoon, the president would announce his support, and the Senate and the House would get it done and it would be on the president’s desk," Schumer said Tuesday. "He didn’t do that. So we’re going to have to start on a new basis and so the wall offer is off the table." 
 
 In the now-famous cheeseburger summit last Friday with Trump, Schumer offered a large increase in border wall spending as a condition for a broader deal to help Dreamers. But after that offer was rebuffed — prompting the three-day government shutdown — the president has now “missed an opportunity to get the wall,” one Democratic aide said. 
 
 Hogan Gidley, a White House spokesman, said Tuesday that the Schumer offer “never existed.” 
 
 “You can't rescind money you never really offered in the first place,” he said on Fox News. 
 
 But Senate Majority Whip John Cornyn (R-Texas) refuted that, saying the offer Schumer made to Trump totaled roughly $25 billion. A spokesman for Schumer declined to confirm that figure. 
 
 Some key Republicans — including Sen. Jeff Flake of Arizona, a key GOP immigration negotiator — had already considered using the promise of border wall funding totaling more than $1.6 billion to lure more conservative votes. A Dreamer plan written by a bipartisan group of six senators, including Flake, had included Trump’s $1.6 billion request as part of a broader, $2.7 billion border security package. 
 
 “Sen. Schumer’s already indicated that he would go for more. Republicans will go for more,” Flake said. “It’s just how much more we can get from the Democrats.” 
 
 Republicans aligned with Trump are unlikely to go for any bill that does not offer a major boost in border wall funding, given the president’s strong feelings about the issue. Moreover, Sen. Tom Cotton (R-Ark.) said he was skeptical of Schumer’s recollection of the meeting and the border wall offer anyway. 
 
 “They claim that some crazy deal was made,” Cotton said of Democrats. “And then when we say no deal was made, they accuse Republicans and the president of reneging.” 
 
 But providing border wall money could also push away more liberal Democrats, who prefer to completely restart negotiations rather than start from any existing bill, even a bipartisan one like the proposal written by Durbin and Sen. Lindsey Graham (R-S.C.). 
 
 “Discussions were had coming up to Friday night are interesting for context,” said Sen. Brian Schatz (D-Hawaii). But now, he said, “we start from a blank sheet of paper.”

 In a video posted on Twitter, Trump attacked Democrats as “absolute hypocrites” and claimed they’ve supported funding border barriers in the past but won’t do so now because of their opposition to him. 
 
 The video showed images of people rushing the border and included clips of Senate Minority Leader Charles E. Schumer (D-N.Y.), former secretary of state Hillary Clinton and former president Barack Obama speaking in opposition to illegal immigration and in favor of border security. 
 
 “We need to have the wall. We need border security. Whatever it takes to get border security, I will do it,” Trump says in the video. “I pledged that a long time ago, and I will pledge it always.” 
 
 The video had a caption saying “Let’s not do a shutdown, Democrats — do what’s right for the American People!” 
 
 The video came two days after Trump declared during an Oval Office meeting with Schumer and House Minority Leader Nancy Pelosi (D-Calif.) that he would be “proud” to shut down the government to get the wall money he wants. 
 
 Since then, Democrats have attacked him relentlessly on the issue, with Schumer repeatedly accusing the president of throwing a “temper tantrum” as he threatens to lead the government into a partial shutdown in pursuit of what critics say is a costly and unnecessary wall. 
 
 Trump is demanding $5 billion for his border wall for 2019, while Democrats are unwilling to give him more than $1.3 billion for border fencing. Democrats said Thursday that they won’t budge. 
 
 “President Trump is willing to throw a temper tantrum and shut down the government unless he gets his way,” Schumer said on the Senate floor. “I want to be crystal clear: There will be no additional appropriations to pay for the border wall. It’s done.” 
 
 Funding for federal agencies including the Homeland Security Department runs out Dec. 21 at midnight, unless Congress passes a spending bill before then and Trump signs it. Other agencies affected include the Justice, Interior and Agriculture departments, totaling 25 percent of government spending that is controlled by Congress. 
 
 Other major agencies, including the Pentagon, have already been funded through September. 
 
 On Capitol Hill, confusion and uncertainty reigns about how the dispute will end. 
 
 Lawmakers headed home for a long weekend Thursday no closer to a solution, leading one key lawmaker to suggest that Congress might have to fall back on passing another short-term spending bill, kicking the can down the road once again because of an inability to compromise. The Homeland Security Department and other agencies are already operating under a two-week short-term spending bill. 
 
 Senate Appropriations Chairman Richard C. Shelby (R-Ala.) suggested Congress might have to extend funding until Dec. 26 or even Jan. 3 — right before a new Congress is sworn in and Democrats take control of the House. Shelby said other options could include short-term extensions until later in January, February or May, or all the way through the end of the fiscal year Sept. 30, which is the solution Democrats have proposed. 
 
 “We’re at an impasse,” Shelby said. “Something’s going to happen, or we’re going to have a CR or a shutdown.” A CR is a “continuing resolution” that extends government spending at existing levels. 
 
 However, Democrats said no one had discussed the shorter-term options with them. 
 
 House members are not scheduled to return to the Capitol until Wednesday evening, two days before the shutdown deadline, prompting sniping from some senators. 
 
 “I don’t understand why people don’t come to work and work all the way through December when the taxpayers are paying them,” said Sen. Shelley Moore Capito (R-W.Va.). “I mean, finish your job.” 
 
 Trump also claimed in an earlier tweet Thursday that “money we save” from a new trade deal with Mexico and Canada would make good on his long-standing promise to have Mexico pay for the wall — an assertion backed by no verifiable evidence. 
 
 “I often stated, ‘One way or the other, Mexico is going to pay for the Wall,’ ” Trump wrote on Twitter. “This has never changed. Our new deal with Mexico (and Canada), the USMCA, is so much better than the old, very costly & anti-USA NAFTA deal, that just by the money we save, MEXICO IS PAYING FOR THE WALL!” 
 
 Mexican officials have said there was no discussion in the trade deal negotiations of mechanisms under which Mexico would pay for the wall. 
 
 Schumer and Pelosi both ridiculed Trump for his claim. 
 
 “It doesn’t make any sense,” Pelosi told reporters at a news conference. “Maybe he doesn’t understand how a trade agreement works. . . . I think the Oval Office is an evidence-free zone.” 
 
 Pelosi, who is likely to become House speaker in January, also pointed out that Congress has yet to ratify Trump’s new trade deal. 
 
 Schumer, meanwhile, suggested on the Senate floor Thursday that if Mexico is truly funding the wall, Congress does not need to spend any money on it. 
 
 Trump spent much of the 2016 campaign promising American voters that Mexico would somehow pay for the construction of a wall along the U.S.-Mexico border, a demand that angered Mexican officials but enthralled his supporters. Since becoming president, though, Trump has sought U.S. taxpayer money to fund the wall’s construction and threatened to shut down parts of the U.S. government if lawmakers do not acquiesce.

– President Trump's Oval Office argument with Chuck Schumer and Nancy Pelosi was the talk of the town on Tuesday, and on Wednesday the president picked up where he left off. Trump took to Twitter to continue his push for border-wall funding, this time trying to bolster his argument by citing a mass shooting Tuesday at a Christmas market in Strasbourg, France. Politico notes the attack was located near the France-Germany border. Trump tweeted, "Another very bad terror attack in France. We are going to strengthen our borders even more. Chuck and Nancy must give us the votes to get additional Border Security!" Then, in a second tweet, "The Democrats and President Obama gave Iran 150 Billion Dollars and got nothing, but they can’t give 5 Billion Dollars for National Security and a Wall?" Senators are currently willing to approve $1.6 billion in funding for border security, though that money couldn't be put toward wall construction. As for Trump's $150 billion figure, it's a reference to the amount of frozen assets Iran got access to when sanctions were lifted as part of the nuclear deal; Politico reports then-Treasury Secretary Jack Lew calculated a lower impact of $56 billion. (The suspect in the Strasbourg attack may have already fled France.)
