Lana Zak, ABC News Washington - "Unfortunately the President just got up and walked out. We saw a temper tantrum because he couldn't get his way," Senator Charles Schumer said.

"We heard once again that Democratic leaders are unwilling to even negotiate. They demanded once again that before any negotiations could begin that we would have to agree to reopen the government and the President called the question in the meeting," Vice President Mike Pence said. 

The President tweeted that his meeting with Democratic leaders was a total waste of time.

But now in its 19th day the partial shutdown is becoming increasingly painful for 800,000 federal workers. 

On Friday many will be faced with the reality of the U.S. government not making payroll. The President insists they still support him.

"These are terrific patriots. A lot of them agree with what I'm doing," President Trump said. 

But Democratic leaders Nancy Pelosi and Chuck Schumer appeared with federal workers who laughed at the President's claim.

"We oppose being collateral damage. We oppose the use of extortion instead of reasoned debate," President of the American Federation of Government Employees David Cox said.

"If something happens to any of our professionals behind this distraction, blood will be on your hands.  Stop playing chicken with our lives," Eric Young, FEMA, said. 

Negotiations continue between the President and Congressional Democrats and Republicans at the White House, but according to Pelosi these negotiations are reliant on the President.

"We have been negotiating. The White House seems to move the goal posts. Every time they come with a proposal, they walk away from it. Pretty soon, these goalposts won't even be in the stadium," Pelosi said. 

The President heads to the border Thursday.
