With the threat of a government shutdown looming, a two-week extension to fund the government through Dec. 22 was introduced in the House on Saturday.

Rep. Rodney Frelinghuysen, R-N.J., chairman of the House Appropriations Committee, announced the continuing resolution as funding is set to expire on Friday.

"Continuing funding for federal operations is critical to our nation's stability, our economy, and for the well-being of the American people. It is a necessary step to ensure the programs and services that all Americans rely on are maintained and available to all," Frelinghuysen said in a statement. "It is absolutely vital that all 12 of the regular Appropriations bills be negotiated and signed into law. This CR will allow for additional time for a deal to be reached on top-line spending levels for this fiscal year. Once this agreement is made, my Committee will rapidly go to work with the Senate to complete the final legislation."

A political spat between President Trump and Democratic leadership has cast some doubt on whether a spending deal can be agreed upon in time.

Senate Minority Leader Chuck Schumer, D-N.Y. and House Minority Leader Nancy Pelosi, D-Calif., skipped a meeting at the White House on Tuesday after Trump complained about their willingness to negotiate.

"Problem is they want illegal immigrants flooding into our Country unchecked, are weak on Crime and want to substantially RAISE Taxes. I don’t see a deal!", Trump said in the tweet that prompted Schumer and Pelosi to pull out of the meeting.

On immigration, Trump was referring to the Deferred Action for Childhood Arrivals program, a fix for which some Democrats have indicated is necessary for them to support a government funding extension. DACA, which provides legal protections to illegal immigrants who arrived in the U.S. when they were minors, is set to expire in March.

The second-ranking Democrat in the Senate, Dick Durbin of Illinois, is a leading force in opposing any spending legislation if there is no fix to protect so-called "Dreamers."

“That’s my position. There’s too much at stake here. We can’t let this to slip into January, February with a March 5 deadline. It should be done, it can be done, easily, simply and quickly,” Durbin told the Washington Post.

Meanwhile, Trump reportedly told confidants that a government shutdown could be good for him, winning political points with his base, which adores his hard-line stance on immigration.

The Washington Post reported that Trump was unhappy with how he looked like a "chump" after striking a deal with Democratic leaders in the fall to extend government spending and increased the debt limit for three months.

White House Legislative Affairs Director Marc Short, among other aides, denied the report.

“He’s not advocating for a shutdown in any way. We want to make sure our military is funded. We want to make sure our priorities are funded. That’s why we invited [Democrats] over to have a conversation about a deal,” Short said Thursday.
