Idaho Senator Larry Craig wasn't allowed to withdraw his guilty plea, but he had his mind set on withdrawing something, so he's not resigning from the Senate as he had promised/announced/broadly hinted at previously.
One reason he gave was that he can do much more good for Idaho than a rookie senator because after many years in Congress, he sits on all of them important committees. I guess it slipped his mind that his Republican brethren already made him step down from all those committees. And they will no doubt continue to put pressure on him to step down, as he has put himself under the public's magnifying glass. When he shamefully continued his pattern of homophobic votes recently by voting against extending hate-crimes legislation to gay, lesbian and transgendered victims, the media took notice. And they will continue to do so - Craig will be a damned homo if he does, a damned homo if he doesn't. And they will dig up every trick he ever turned.
I am sure his fellow Republican Senators would prefer he followed Mark Foley's example, so let's dedicate Amy Winhouse's "Rehab" to Larry Craig, shall we?
