Rep. Jim Sensenbrenner, Republican of Wisconsin announced he will not seek reelection in 2020. Now in his 21st term, he has the 2nd longest tenure among current House members, after Don Young of Alaska. His retirement is the 2nd of the day, after Texas Rep. Bill Flores. The decision comes about a week after his fellow Wisconsin Rep. Sean Duffy announced he would resign from Congress in late September.
Wisconsin's 5th district covers much of the northern and western suburbs of Milwaukee. It is a conservative district; Donald Trump won here by 20% over Hillary Clinton in 2016.
