Kramer filed paperwork with the Wisconsin Government Accountability Board stating that he would not be a candidate in the fall for the Assembly seat covering parts of conservative Waukesha County. The document was signed March 14 but not submitted to the agency overseeing elections until 10 days later.
Kramer, a Republican, was unanimously voted out of his position as majority leader on March 4 after he was accused of sexually harassing two women while in Washington, D.C., for a fundraiser. One of the women is a lobbyist and the other is a legislative staff member.
Pressure was building on Kramer to resign the seat he's held since 2007. Assembly Speaker Robin Vos called on him to step aside, and Gov. Scott Walker said if the allegations against him were true, he should not hold office.
Kramer, 49, was chosen as majority leader, the second-most powerful position in the Assembly, in September to replace Scott Suder, who had resigned to take a position with Walker's administration.
Kramer checked himself into an unspecified treatment facility on March 1, the day after the allegations were made public. An email sent to Kramer's chief of staff Cameron Sholty seeking comment Monday was not immediately returned.
No criminal charges have been filed against Kramer, but an internal human resources complaint has been brought against him and is being investigated.
Republicans voted to replace Kramer as majority leader with Rep. Pat Strachota. Strachota, who is also not seeking re-election, presided over the final two session days of the Assembly this month. The Assembly adjourned for the year early Friday morning.
Republicans hold a 60-39 majority in the Assembly. All 99 seats are up for election in November.
Kramer is the 13th incumbent to announce he will not be running again. Eight of them are Republicans and five are Democrats. Of those, four Democrats and two Republicans are running for other offices.
