The funding fight was kicked back to the Senate on Thursday night after House Republicans easily approved a measure adding more than $5 billion for the border as well as disaster recovery money to a seven-week continuing resolution.

The Senate will come into session Friday at noon, giving Congress only 12 hours to prevent a partial lapse in funding as both sides dig in and ratchet up their shutdown rhetoric.

Democrats have insisted they will not back a bill providing the $5 billion for Trump’s wall, which would prevent the measure from advancing in the Senate.

“The Senate will receive and begin consideration of the House-passed bill tomorrow afternoon. Expedited consideration will require consent,” said David Popp, a spokesman for McConnell.

GOP senators say they were given guidance on Thursday to expect a possible vote on Friday afternoon, assuming the House was able to pass a bill. McConnell will need Democrats and all Republicans to agree to speed up votes, otherwise the funding fight automatically drags into the holiday weekend.

Without the votes to pass the bill through the Senate, lawmakers are stuck with two options: reject the House bill outright or strip out the extra border money, send it back to the House and see if conservatives and Trump cave.

Mike Simpson MIchael (Mike) Keith SimpsonDuring a time of uncertainty, Great American Outdoors Act deserves our support Dentists want coronavirus testing kits before reopening MLB, Congress play hardball in fight over minor leagues MORE (R-Idaho), a senior appropriator, predicted the Senate takes up the House bill, strips out the $5 billion in wall funding and then kicks the clean measure back to the House.

“I don't think it passes. Then we're in a shutdown,” he added.

A House GOP member who is close to the negotiations said that “there's a good probability that we're shutting down.”

If the partial shutdown begins, it would be the third shutdown this year, after a days-long shutdown in January and a brief closure in February.

Thursday’s rollercoaster ride represented a dramatic turnaround from Wednesday night, when the Senate passed its seven-week continuing resolution by a voice vote, senators were singing Christmas carols on the floor and GOP leadership appeared confident that Trump would sign the stopgap.

That quickly unraveled on Thursday after Trump — taking fire from conservative pundits and lawmakers for signaling he would accept a bill without extra border money — reversed course and told House lawmakers at the White House that he would not sign the bill.

Conservatives have urged Trump to double down, despite no clear path to getting wall funding, arguing he campaigned on the issue and it is crucial to his base.

“This president for two years has told this Congress that border security is a top priority. ... I totally understand his frustration,” said Sen. David Perdue (R-Ga.). “It’s time to get this done.”

Asked how both sides can come to a deal before the deadline, Perdue said senators should be prepared to work through the weekend and “stay here and let’s wrestle this thing out.”

Democrats, accusing Trump of creating “chaos” and throwing a “temper tantrum,” are poised to take back the House early next month and have warned that, if the government partially shuts down, they will wait roughly two weeks and pass a clean continuing resolution.

“It's a shame that the president who is plunging the nation into chaos is throwing another temper tantrum and is going to hurt lots of innocent people. ... It will not get him his wall,” Schumer said.

And while conservatives are clamoring for Trump to dig in ahead of the shutdown deadline, many GOP senators appeared exasperated by the chances of a partial shutdown and skeptical that it would result in a win for Trump or the party.
