FY 2016 Omnibus: Talks are still stalled over policy riders and tax extenders. A short–term CR of a few days to a week is now likely. Whenever an omnibus bill is filed, under House operating procedures, the House won't vote on it until two days after it is filed. So, if an omnibus were filed today the House would vote Thursday. If it is filed tomorrow, the House would vote Friday, etc. Once the House votes, the Senate will likely need to invoke cloture, which normally takes two days (a cloture vote occurs two days after a motion to invoke cloture is offered).
President Obama would sign a continuing resolution that would extend government funding by an "extra day or two" while lawmakers "go through the legislative mechanics" of constructing and passing an omnibus spending measure, Press Secretary Josh Earnest said.

“House leaders of both parties said Tuesday that compromise on a government spending bill remained out of reach, with Republicans indicating a short-term funding measure would be necessary before Friday’s deadline.
“Top Democrats said that conservative amendments to the year-end bill have stalled talks, risking of a Dec. 11 shutdown.
“Republicans have vowed to stay in town as long as it takes to finish work on the omnibus and said they would not allow the government to shut down.”
In addition, the House Freedom caucus is now pushing for a six-week CR because they believe pushing off until next year decisions gives them more leverage.

“Rep. Matt Salmon (R-Ariz.) said he would like Congress to approve a six-week, stopgap spending bill to give more time to try to force Democrats to accept the language to tighten restrictions on Iraqi and Syrian refugees. Salmon said many members of the Freedom Caucus would vote for the omnibus if it included this language, but senior Republican leadership aides doubt that is true.”
