Sept. 25 (UPI) — The White House has warned federal workers there will be more mass firings if Congress is unable to agree on a stopgap funding measure by the end of the month.

The warning came in the form of a memo from the White House Office of Management and Budget sent to federal agencies and viewed and first reported on by Politico.

CNN and The New York Times also viewed the memo sent Wednesday night.

The OMB asked the federal agencies to identify programs that would lose funding and have no other sources of funding if the stopgap measure measure fails to pass by Sept. 30. Programs that don’t align with President Donald Trump‘s priorities would then face a permanent elimination of jobs.

“Programs that did not benefit from an infusion of mandatory appropriations will bear the brunt of a shutdown,” the memo said.

“We remain hopeful that Democrats in Congress will not trigger a shutdown and the steps outlined above will not be necessary.”

The House passed a short-term funding measure Friday, but the bill failed in the Senate. Senate Democratic leader Chuck Schumer said his party wouldn’t support the legislation unless it included provisions extending Affordable Care Act subsidies set to expire at the New Year.

Schumer and House Democratic leader Hakeem Jeffries were expected to meet with Trump Tuesday, but the president canceled the meeting, saying he didn’t like their list of “demands.”

Schumer said Wednesday’s OMB memo was “an attempt at intimidation.”

“Donald Trump has been firing federal workers since day one — not to govern, but to scare,” he said. “This is nothing new and has nothing to do with funding the government. These unnecessary firings will either be overturned in court or the administration will end up hiring the workers back, just like they did as recently as today.”
