“We're going to pass a short-term continuing resolution over into March,” McConnell said on CNN’s “State of the Union.”

A Senate Democratic aide, however, said a deal is not final and "there are still outstanding issues."

Government funding is due to expire at the end of Tuesday. The Senate is expected to pass the longer-term measure by unanimous consent before then.

Reid attempted to pass a $1.1 trillion omnibus spending bill that would have funded the government through the end of fiscal year 2011. But he had to pull the bill from the Senate floor after nine Republican senators who had pledged to vote for it yanked their support at the last moment, according to Democratic aides.

The House earlier this month passed a continuing resolution to fund the government through Sept. 30.

Republicans wanted a shorter stop-gap spending measure to give Republicans an opportunity to cut federal spending when they take over the House in January.

On Thursday, McConnell proposed a one-page resolution funding the government through Feb. 18.
