MADISON, Wis. (WRN) — The FBI is reportedly opening an investigation into Wisconsin’s handling of the 2020 presidential election.

The Milwaukee Journal Sentinel reports an FBI agent interviewed Wisconsin Elections Commission deputy administrator Robert Kehoe and is allegedly focusing on complaints that were previously made by President Donald Trump and his supporters. It is unclear what the FBI may be looking at, but similar investigations have been opened across the country in Democratic counties and cities.

President Trump lost Wisconsin in 2020 to Joe Biden by 21-thousand votes, and that win has been upheld by two separate recounts, a state audit, and multiple court rulings.
