"The staffs were making great progress until the president stepped in. We were very close on a number of issues," Schumer told reporters.

Congress will need to pass either a stopgap bill or a long-term funding deal by Dec. 8 or the government will run out of money.

But the New York Democrat and the White House have been locked in a war of words about a potential deal after the president said on Twitter that he was meeting with "Chuck and Nancy" on keeping the government open but "I don't see a deal."

Schumer and Pelosi pulled out of the meeting, saying the "best path forward" was to keep negotiating with Republican leadership.

Schumer doubled down on that during his Tuesday afternoon press conference, noting that government funding negotiations run more smoothly when Trump doesn't participate.

"When the president stays out of it we seem to do much better, the four leaders. ... That's how we did it the last time the government funding expired," he said.

He added that because Republicans need Democratic help to fund the government "bipartisanship is required. ... That means serious, mature negotiations."

GOP leadership will need 60 votes to pass a government funding bill in the Senate, including the support of at least eight Democrats.
