Long-serving Republican Sen. Larry Craig of Idaho, embroiled in a sex scandal and finding little support from his party, will announce on Saturday he will resign from the Senate, CNN reported on Friday.

Quoting a Republican source in Idaho, CNN said Craig would leave office on Sept. 30.

Republican Idaho Gov. C.L. “Butch” Otter would pick a successor to complete Craig’s term, which runs through next year. It is expected he would choose a Republican, thus maintaining the current 51-49 Democratic control of the Senate.
