(AURN) -- Attorney General Eric Holder is still not off the hook.  A House committee could today vote on whether to hold Holder in contempt of Congress for failing to turn over more Justice Department documents on a flawed gun-smuggling program that began in 2006.  Holder has already turned over tens of thousands of documents, and has offered many more Tuesday, but his offer was rejected.  Some lawmakers say it's a political witch hunt against the Democratic Attorney General.
