Senate Democratic leaders have moved to clear former Sen. Chuck Hagel’s (R-Neb.) nomination by Thursday even as Republicans are ramping up their threats to block it.

Senate Majority Leader Harry Reid (D-Nev.) said Monday he would move Hagel’s nomination as Defense secretary quickly to the floor following a Tuesday vote by the Senate Armed Services Committee.

Reid said he expected a floor vote on Wednesday or Thursday and was “confident” that there would not be a filibuster, despite the Republicans’ rhetoric.

“There’s never in the history of the country ever been a filibuster on a Defense secretary, and I’m confident there won’t be on this one,” Reid said.
