Idaho Sen. Larry Craig has lost his latest attempt to withdraw his guilty plea in a Minneapolis, Minnesota airport men's room sex sting.
A three-judge panel of the Minnesota Court of Appeals on Tuesday rejected the Republican's bid to toss out his disorderly conduct conviction.
Craig was arrested in June 2007 in a Minneapolis airport bathroom stall by an undercover officer who said the senator solicited sex.
He pleaded guilty to the misdemeanor and paid a fine, but changed his mind after word of his arrest became public. Craig insisted he was innocent, but the case effectively ended his political career.
Craig's attorney argued before the appeals court this September that there was insufficient evidence for any judge to find him guilty.
Prosecutors said his guilty plea should stand.
