UPDATE: Senate invokes cloture on omnibus bill

The Senate has just voted to limit debate on a $1.1 trillion omnibus appropriations bill, setting up a final vote sometime tomorrow afternoon.

Democrats pulled together exactly the 60 votes needed to invoke cloture, with a few members of each party switching sides.

From listening to the roll call, it seems Bayh (Ind.), Feingold (Wis.) and McCaskill (Mo.) were the Dems to vote against the measure, while Cochran (Miss.), Shelby (Ala.) and Collins (Maine) were the Republicans to vote aye. We'll update that count when an official roll call is posted online.

The bill includes $447 billion in 2010 appropriations for a number of cabinet departments, as well as about $650 billion for programs like Medicare and Medicaid.

The House passed similar legislation earlier this week.

UPDATE: Our initial vote count was correct. Here's the full roll call.
