Washington (CNN) Time is running out with just five days to go before funding expires for several key federal agencies and no deal in sight to avert a partial government shutdown.

On Capitol Hill, Republicans and Democrats alike have made clear they don't want a shutdown, but lawmakers left Washington last week without a resolution in an ongoing standoff over funding for President Donald Trump's long-promised border wall. The administration and congressional Democrats appeared to be no closer to reaching an agreement over the weekend.

White House senior adviser Stephen Miller said on Sunday the administration would do "whatever is necessary to build the border wall," saying "if it comes to it, absolutely," when asked on CBS's "Face the Nation" if that would mean a partial shutdown. But Senate Democratic Leader Chuck Schumer insisted on NBC's "Meet the Press" on Sunday that the President is "not going to get the wall in any form," saying the votes aren't there in the House or the Senate.

The window is narrow this week for Congress to take action. The Senate will be back on Monday, but the House of Representatives isn't expected to return until Wednesday evening. That leaves little time before funding runs out at midnight on Friday for a number of federal agencies, including the Department of Homeland Security, the Justice Department, and other parts of the government.

Trump wants $5 billion in wall funding, but that number is a non-starter for Democrats. Any spending legislation would need to pass with at least some Democratic votes since it would have to clear a 60-vote threshold in the Senate where Republicans only have a 51-seat majority.
