Milwaukee’s election leader has been ousted by the mayor in a surprise move that comes just six months before Wisconsin’s largest city will be in the spotlight in the presidential swing state.

Milwaukee Mayor Cavalier Johnson announced Monday that he would be replacing Milwaukee Election Commission Executive Director Claire Woodall with her deputy, Paulina Gutierrez.

Milwaukee has been at the center of attention in Wisconsin, a state known for close elections and where four of the past six presidential contests have been decided by less than a percentage point.

The change has nothing to do with how Woodall ran elections, but instead had to do with “other issues internal to the election commission office and to city government that raised concern,” said the mayor’s spokesperson Jeff Fleming. He declined to say what those issues were.

(Woodall) has described being harassed and threatened after the 2020 election via email, phone calls and letters to her home — threats serious enough that she has an assigned FBI agent to forward them to.
