Lawmakers in the upper chamber appear to be coalescing around a deal that would fund the government into January and extend the nation's debt ceiling into February. The legislation is also expected to make minor tweaks to ObamaCare and establish a joint budget committee to create a replacement for the sequestration budget cuts.

On Monday, McConnell expressed optimism that a deal was on track.

“It’s safe to say we’ve made substantial progress and we look forward to making more progress in the near future,” McConnell said.

The Senate Republican Conference is set to meet Tuesday morning to discuss the proposal. The meeting had been originally set for Monday night, but not enough senators could make the meeting.
