Senate Minority Leader Chuck Schumer, D-N.Y., warned the White House and Republicans on Monday against trying to include funding for the border wall in a spending bill aimed at avoiding a partial government shutdown after Friday.

"So far, the discussions between our two sides have been constructive, and have been progressing nicely. Without interference, I believe our two parties can come to an agreement together by the end of the week," Schumer said. He added that his negotiations with Speaker Paul Ryan, Senate Majority Leader Mitch McConnell, and House Minority Leader Nancy Pelosi have been "going very well."

However, Schumer said that the White House threw "a monkey wrench" into negotiations.

"I'll caution that if the administration insists on poison pill riders or extraneous funding requests, then our tasks could get sidetracked," Schumer said, calling border wall funding a "non-starter" for Democrats.

"If the administration insists on funding for a wall in this bill, it will endanger the prospects of the bill passing and raise the prospects of a government shutdown," Schumer said before he listed the reasons why the wall is a "pointless waste of taxpayer money."

The top-ranking Senate Democrat also hit Trump over his actions during the first 100 days in office, which is set to conclude on Saturday. Schumer said repeatedly that Trump has broken his promises to working-class voters and even said that he has "abandoned" his promises altogether.

"It's appropriate time to take stock of what this president has accomplished so far," Schumer said. "Unfortunately, it's not much."

"In the first 100 days, so many of the promises the president has made to working families throughout the campaign have been broken outright or remain unfulfilled," Schumer said. "Democrats are going to hold the president accountable for the promise he made to working-class voters ... Unfortunately, he's abandoned those promises in favor of a hard-right, special-interest agenda."

He also panned the president over his pledge to "drain the swamp" in Washington and press that, instead, Trump is "filling it up to the brim" with billionaires.
