The move marks a sharp reversal for Schumer, who earlier this year sided with Republicans to keep the government open and faced fierce backlash from Democrats for doing so, Newsmax reported.

In an interview with The Associated Press on Thursday, Schumer said the situation is now different than it was in March.

“Things have changed” since that earlier vote, Schumer said.

He argued that Republicans have since passed President Donald Trump’s tax breaks and spending cuts legislation, which included cuts to Medicaid and other programs, and that Democrats are now unified — unlike in the spring, when his vote angered the party’s base.

Schumer said he and House Democrat Leader Hakeem Jeffries are now united in opposing any government funding bill that does not include key health care provisions and a guarantee those provisions will not be rolled back.

The new line from Schumer reflects a willingness to endure a shutdown rather than compromise on the party’s demands.

A shutdown, he said, would not necessarily worsen tensions with the White House, which he described as already hostile.

“It will get worse with or without it, because Trump is lawless,” Schumer said.

Republicans are considering a short-term stopgap measure to keep the government running past Sept. 30.

But Schumer said Democrats will not go along unless the plan includes health care protections and a commitment to keep foreign aid funding in place.

Republicans insist Democrats will bear responsibility if the government closes, and Senate Majority Leader John Thune, R-S.D., has said repeatedly that Schumer must put forward a concrete health care proposal if he expects a deal.

Thune pointed to the looming expiration of expanded tax credits for health insurance purchased through the Affordable Care Act and said some Republicans are open to extending those credits before they expire at the end of the year.
