You might recall that Vitter is the adulterer who was caught paying prostitutes, and then recently was found to have a staffer accused of cutting his girlfriend with a knife (and Vitter knew, and did nothing about it until it went public). From AP:
Republican Sen. David Vitter of Louisiana says he supports conservative organizations challenging President Barack Obama's citizenship in court.
Vitter, who is running for re-election, made the comments at a town hall-style event in Metairie, La., on Sunday when a constituent asked what he would do about what the questioner said was Obama's "refusal to produce a valid birth certificate."
