Another one bites the dust...

Idaho Republican Sen. Larry Craig's decision to quit spares his party the embarrassment of an indefinitely prolonged scandal following his arrest during a sex sting in a Minneapolis airport bathroom.

Craig will announce his resign effective Sept. 30, at a news conference in Boise Saturday morning, GOP officials in Idaho and Washington told The Associated Press.

Still, opting to wait a month before officially bowing out raises questions of what Craig hopes to accomplish in Washington once the post-Labor Day session begins.
