Wisconsin State Rep. Bill Kramer, R-Waukesha, notified the Government Accountability Board he will not seek re-election in November.
Kramer was ousted from his majority leader position three weeks ago after being accused of sexual harassment.
After a Washington, D.C., fundraising trip, Kramer was accused of groping a woman in a bar and passing inappropriate comments about a woman on the return flight. Kramer checked himself into an unspecified rehabilitation center following the allegation and has been unavailable for comment.
No criminal charges have been leveled against Kramer.
Assembly Republicans held a closed caucus March 4 and unanimously voted to remove Kramer from his leadership position and replace him with state Rep. Pat Strachota, R-West Bend.
Strachota had already announced she will not run for re-election in November for her Assembly seat and will have to be replaced after the elections.
All 99 state Assembly seats are up for re-election in November.
