"Sen. David Vitter (R-La.) was Capitol Hill's invisible man yesterday, lying low even as his ties to the notorious "D.C. Madam" threatened to become a political crisis for the conservative lawmaker... Vitter was nowhere to be found yesterday, and most sources believed the freshman senator remained in Louisiana to avoid the press onslaught."

Maybe he's hiding from his wife who threateend him with a Bobbit-ing if he was ever unfaithful.

But morel ikely it's this little quote that's haunting him

Sen. David Vitter (R-LA) first got his start in Congress after replacing former Rep. Bob Livingston (R-LA), who "abruptly resigned after disclosures of numerous affairs" in 1998. At the time, Vitter argued that an extramarital affair was grounds for resignation:
