The White House is engaged in a last-ditch effort to avert a government shutdown, negotiating with Senate Democrats a deal that could split off money for the Department of Homeland Security from a larger spending bill.

No agreement has been reached between Senate Minority Leader Chuck Schumer (D-NY) and the White House, according to a source familiar with the negotiations, but the development signals President Donald Trump’s interest in averting an extended lapse in funding at midnight on Friday.
