The Trump administration will start mass layoffs of federal workers if the president decides negotiations to end the government shutdown are “absolutely going nowhere,” a senior White House official has said.

Kevin Hassett told CNN he still saw a chance that Democrats would back down, but added that Trump was “getting ready to act” if he has to.

No tangible signs of negotiations have emerged between congressional leaders since Trump met with them last week. The shutdown began on 1 October, after Senate Democrats rejected a short-term funding measure that would keep federal agencies open through to 21 November. Democrats are demanding that funding include healthcare measures for low-income Americans.

“They’ve refused to talk with us,” Senate Democratic leader Chuck Schumer told CBS, saying the impasse could be solved only by further talks between Trump and the four congressional leaders.
