Congressional leadership is publicly mulling another stopgap spending bill to prevent a third government shutdown as lawmakers race to finalize mammoth funding legislation.

"It just means we're going to be here into the weekend, perhaps, and there may have to be some measures taken to keep the lights on, but we'll get it done," he told reporters on Tuesday.

Asked if one of those measures would be a stopgap bill, he added: "That would be the one thing we could do, yeah."

The talk of needing another short-term funding bill comes as lawmakers struggle to iron out the final hurdles to getting a deal on the omnibus, which would fund the government through the end of September.

Congress has until Friday at midnight to pass legislation to prevent the third partial government closure in as many months.

Lawmakers had hoped to unveil the funding bill Monday night, setting up a vote in the House for Wednesday, but that was delayed as negotiators held a round of late-night talks.

They are now hoping to unveil the bill Tuesday, with a vote in the House on Thursday.

That could push the Senate's debate past the Friday deadline unless leadership can get every senator to agree to speed up the votes.

He refused repeated requests to move up a vote on a three-week CR and drove the chamber into a middle-of-the-night vote.

Asked on Tuesday if he would let leadership speed up the votes on the omnibus, he told The Hill "we haven't decided yet."

If the House passes the omnibus on Thursday, the earliest the Senate could hold an initial vote is early Saturday morning — roughly an hour past the funding deadline.

Pelosi told reporters Tuesday that a short-term CR to give the Senate enough time to navigate around its procedural hurdles was being discussed.

“More prominently discussed is if the Senate has all of these procedural things it has to do it might not be finished in time, and maybe [we’ll need] a short-term [bill] just to see it through — should we come to agreement on the other things," she said.
