WASHINGTON (CNN) - The President's incoming acting chief of staff Mick Mulvaney said Sunday that "it is very possible that the shutdown will go beyond the 28th and into the new Congress" during an interview on "Fox News Sunday."
A spokesman for Senate Democratic leader Chuck Schumer told CNN Sunday that "if Director Mulvaney says the Trump Shutdown will last into the New Year, believe him — because it's their shutdown."
Schumer made a counteroffer on border security, according to a Democratic source familiar with the negotiations -- before Saturday when he met with Vice President Mike Pence -- to Appropriations Chairman Richard Shelby and that was rejected by the White House. Pence then made his own offer on Saturday, which was rejected by Schumer.
Schumer and Shelby have been having side discussions, but they don't appear to have yielded much progress given the differences between Schumer and the White House, the source added.
The Senate adjourned Saturday afternoon with no deal to re-open the government, and while there will be a pro forma Senate session on Monday, the next actual session is not scheduled until Thursday.
Lawmakers can travel home for Christmas and won't have to worry about being called back to vote until a deal can be reached, but GOP leaders told senators that if there is no deal by Thursday, they would not have to return for that session, sources have told CNN.
An estimated 800,000 federal employees may be impacted by the partial shutdown, either by having to work during it while their pay is withheld until it ends or by being furloughed.
