MADISON, Wis. (AP) — A former state Supreme Court justice leading Assembly Republicans’ probe of the 2020 election has sent subpoenas to Milwaukee and Green Bay officials seeking information about private funds they used to run voting operations.

The Milwaukee Journal Sentinel reports that Michael Gableman’s subpoenas are the first issued by state lawmakers in four decades.

The subpoenas sent Thursday seek documents related to the Center for Tech And Civic Life, which gave more than $10 million to more than 200 Wisconsin communities to help cover election costs during the COVID-19 pandemic. Most of the money went to Wisconsin’s five largest cities.

The GOP says the donations are inappropriate. Gableman’s subpoenas require the officials to appear before him Oct. 15 with the documents.
