Louisiana Republican Sen. David Vitter 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 event 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."
According to a video of the event, Vitter responded that he couldn't sue but that he supports others doing so.
He added, however, that the matter could distract from policy issues.
Hawaii officials have repeatedly confirmed Obama's citizenship, and his Hawaiian birth certificate has been made public, along with newspaper birth notices.
