Attorney General Eric Holder likely to be held in contempt of Congress

(CBS News) On Capitol Hill Thursday House lawmakers including some Democrats are expected to hold Attorney General Eric Holder in contempt of Congress for his refusal to turn over some documents related to the Justice Department's "Fast and Furious" gun-running operation.

If the vote passes the question will become how it might be enforced. This is all about Congress still wanting tens of thousands of pages of documents on the scandal.

Most people think it's unlikely they will attempt the criminal route, which would mean Holder's own staff would have to agree to prosecute him if he doesn't hand over documents.

There's another option: Congress can ask a federal court to enforce its subpoena. That's happened before, a court agreed, and before it could go to appeal the two sides compromised and some documents were exchanged.

There are a few interesting developments surrounding the vote. First, at least a handful of Democrats are expected to vote with Republicans in favor of contempt. The National Rifle Association is putting on the pressure and some Democrats have a strong gun rights force in their constituency. Secondly, Democrats say the Congressional Black Caucus is going to lead a walkout during the vote and most Democrats are expected to join.

The Democrats who have publicly indicated they will vote with Republicans include: Utah's Rep. Jim Matheson, Georgia's Rep. John Barrow, West Virginia's Rep. Nick Rahall, and North Carolina's Rep. Mike McIntyre.
