"The Republicans are totally unified", Trump told reporters after that meeting.
Democrats have offered Trump $1.3 billion in new funding for border security, although none for a wall.
In a somber televised plea, President Donald Trump urged congressional Democrats to fund his long-promised border wall Tuesday night, blaming illegal immigration for what he called a scourge of drugs and violence in the USA and framing the debate over the partial government shutdown in stark terms. Hundreds of thousands of federal workers face missed paychecks Friday as the shutdown drags through a third week.
In another tweet, he reiterated the call to "fix" the southern border.
He continued: "I said bye-bye, nothing else works". "They can't watch every inch of the border, so that would help them take more control of the whole situation".
Trump again said he might declare a national emergency "if Chuck and Nancy ... don't agree to the fact that our country really has a problem", he said, referring to Speaker Nancy Pelosi and Senate Minority Leader Charles E. Schumer.
"The president of the United States - having failed to get Mexico to pay for his ineffective, unnecessary border wall, and unable to convince the Congress or the American people to foot the bill - has shut down the government", Schumer said. Following Trump's speech from the Oval Office on Tuesday night, Morgan reiterated his support for the president's plans during an interview with The Washington Post.
"We had this new opportunity to present these leaders differently, and I feel like we've seen that image a lot of times".
Shifting between empathetic appeals and the dark immigration rhetoric that was a trademark of his presidential campaign, Trump asked: "How much more American blood must we shed before Congress does its job?"
Late in the day, Democratic and Republican congressional leaders were to return to the White House to meet with him and renew negotiations that have shown no apparent progress in the past week.
"I'm not for it at all", said one man.
"Maybe he thinks he can bully us".
Senator Doug Jones of Alabama said, "We need to dial back the rhetoric and not use fear".
Hoping to demonstrate flexibility during his almost 10-minute speech from the White House Oval Office, Trump said of the border barrier he wants built: "At the request of the Democrats it will be a steel barrier and not a concrete wall".
Republican Senator John Kennedy of Louisiana called Trump's comments about border security "very appropriate". "It's absolutely false that the border wall is the way to deal with any humanitarian crisis or national security". "Until the American people are convinced we will stop future flows of illegal immigration, we will make no progress". The speech came mere hours after Senate Democrats prevented the chamber from considering bipartisan legislation in an attempt to pressure GOP lawmakers to reopen the government.
