The Republican-hired investigator looking into Wisconsin's 2020 election is no longer seeking to jail the mayors of Green Bay and Madison for allegedly not complying with a subpoena he issued last year.

Wisconsin Republican Assembly Speaker Robin Vos wants the investigation he ordered into the 2020 election to conclude by the end of the month, even as legal fights over subpoenas issued to mayors and the state's top elections official remain unresolved.

A retired state Supreme Court justice hired by Republicans to investigate Wisconsin's 2020 election says the mayors of Madison and Green Bay should face punishment and possibly jail time if they don't meet with him, according to court documents.

Wisconsin's top elections administrator said Wednesday that she never received any formal complaints about Green Bay's mayor ceding authority for running the presidential election in that city to a Facebook-funded consultant.

Republican Wisconsin lawmakers called Tuesday for Green Bay's Democratic mayor to resign following a report on a conservative website alleging he ceded authority for running the election to a paid consultant with ties to Facebook co-founder Mark Zuckerberg.
