Sen. David Vitter (R, La.) just objected to a unanimous consent request, and has promised to object to everything unless he gets a vote on his amendment. The effect will be to delay the cloture vote on the omnibus. It now appears that it will not pass tonight, staffers tell me.

Vitter’s amendment would force members and senators to vote for every pay increase they receive, instead of having member pay increase each year on “auto-pilot.”
