Trump tweeted the threat hours before Senate Democratic Leader Chuck Schumer and House Democratic Leader Nancy Pelosi were to meet with Trump at the White House in an effort to avert a possible partial government shutdown on December 21, when funding for some agencies is scheduled to expire.
"If we close the country, I will take it because we're closing it down for border security and I think I win that every single time", Trump said later.
Rather than reach toward compromise, Trump tried to force Democrats to accept the border wall on his terms.
In her opening comments in the Oval Office, Pelosi said failed budget talks would result in a "Trump shutdown" of government - a phrase that might have inflamed him. "I will take the mantle". I have also been clear from the start that this effort was never about one person-but our entire Democratic leadership team which has been in power for 16 years.
Democrats widely agreed that the pledge meant Pelosi had clinched a comeback to the post she held from 2007 until January 2011, the last time her party ran the House and the first time the speaker was a woman.
The president, however, was less enthused by this designation (#TrumpShutdown is now trending on Twitter), retorting, "A what?"
Trump "wants to score a made-for-reality-TV moment and he doesn't care how many hardworking Americans will suffer for it", Leahy said.
While Pence was also present at the meeting, his noticeable silence has provided for internet fodder.
If there is no deal, Trump would be shuttering the very agency in charge of border security - the Department of Homeland Security.
Democrats will try to make the president regret those words.
"That really just postpones the pain, it doesn't really solve the problem", said Cornyn, explaining that Trump still wouldn't then get the wall funding he wants.
Trump also tweeted that the USA military would build the wall if Democrats refuse to give him the money needed.
Opponents say the wall is not only a waste of money but has been used by the president to whip up xenophobia.
Pelosi and Schumer both implored Trump not to shutdown the government.
Much of the United States government is still funded via a short-term continuing resolution, which will expire on 21 December.
"Elections have consequences, Mr. President", said Schumer. The homeland bill includes about NZ$1.89 billion for fencing and other security measures at the border. While Trump's fellow Republicans control both the House and the Senate until next month, Democratic support is needed to pass any spending legislation. She told Democratic lawmakers back at the Capitol, according to an aide who was in the room, that the wall was "like a manhood thing for him.as if manhood could ever be associated with him".
Republicans were incensed at Pelosi's repeated statements to Trump that he does not have the votes for the wall in the House.
Democratic Leader Nancy Pelosi announced Wednesday evening that she struck a deal with a group of seven rebel Democrats to limit the terms of senior Democratic leaders, paving the way for her election as House Speaker in January. "We have to see what else is entailed", he said.
Later in private, she told the Democrats: "I was trying to be the mom".
Despite the rancor, Senate Majority Leader Mitch McConnell, a Republican, told reporters, "I'd still like to see a smooth ending here and I haven't given up hope that's what we'll have".
The proposed rule change will most certainly push Pelosi over the top in terms of speaker votes - she needs 218 votes on the floor - but a handful have still said they will vote against her.
Taking out two memo cards, he read off figures that he said showed a near end to illegal immigration at portions of the border already featuring high fences.
