Senator Larry Craig (R-ID) is going to retire after his term expires according to The Hill.  CREW filed an ethics complaint against Senator Craig last August after it was revealed he had pleaded guilty to misdemeanor charges in Minnesota.  The Senate Ethics Committee admonished Craig last month:

Sen. Larry Craig (R-Idaho), encumbered by a scandal since last summer, did not file for reelection by his state’s deadline Friday, keeping a promise he made and officially marking the end of his congressional career.

Craig’s political future has been in doubt since his arrest and guilty plea on disorderly conduct charges filed after an incident in a men’s restroom at Minneapolis-St. Paul International Airport last June.
