Google and X, formerly Twitter, recently provided hundreds of files to Michigan prosecutors for their 2020 election subversion probe, complying with search warrants that investigators obtained after CNN revealed secret social media accounts belonging to pro-Trump lawyer Kenneth Chesebro, who played a major role in the fake electors plot.

The previously unreported warrants gave prosecutors access to new Chesebro emails and his private direct messages on Twitter. The warrants make clear that Michigan Attorney General Dana Nessel is still gathering new information in her probe, nine months after she charged the state’s fake electors with forgery and other crimes for signing certificates falsely claiming Donald Trump won the state in 2020.

A top member of her team testified last week that the investigation is ongoing and that Trump is an unindicted co-conspirator in the case, which is not expected to go to trial before the November election.

Michigan is among a number of states to investigate fake electors schemes. Just last week, Arizona prosecutors filed criminal charges against the pro-Trump electors there and allies of the former president who were involved in the efforts to overturn the 2020 election.
