Senate Majority Leader John Thune (R-SD) said on Tuesday that at least two additional Senate Democrats are in discussions to break ranks with Minority Leader Chuck Schumer (D-NY) and vote in favor of funding the government.

The partial government shutdown has now entered its second week. So far, only three Senate Democrats — John Fetterman (PA), Catherine Cortez Masto (NV), and Angus King (ME), an independent who caucuses with Democrats — have joined Republicans in supporting efforts to release federal funds. Senator Rand Paul (R-KY) remains the lone Republican holdout.

But Thune indicated to Fox News that more Democrats are set to join Republicans in support of a clean continuing resolution to reopen the government.

The House has already approved a temporary funding measure to keep the government open through late November, but Schumer has thus far prevented most of his caucus from backing the bill. The measure requires 60 votes to advance in the Senate, meaning at least eight Democrats would need to cross party lines if Paul continues to oppose it — a move Thune suggested is increasingly likely.“Well, we’re only stuck as long as a handful of Democrats decide they want to follow the leader and play politics rather than do the right thing on behalf of the American people and open up the government. That’s where we are,” Thune told Fox News host Harris Faulkner.
