MADISON, Wis. (AP) — 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.

In 2020, former President Donald Trump and others were quick to cry fraud after late-arriving results from Democratic-dominated Milwaukee helped Joe Biden narrowly carry the state by just under 21,000 votes. Recounts demanded by Trump confirmed Biden’s victory.
