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.

According to the new documents provided to Michigan prosecutors, which were obtained by CNN, Chesebro fruitlessly tried to bring several controversial pro-Trump figures to Washington, DC, to watch his “fake electors” strategy unfold on January 6, 2021.

He offered to pay for airfare and lodging at Trump’s upscale DC hotel for former Milwaukee County Sheriff David Clarke, as well as for the founder of the Gateway Pundit conspiracy website, among others. It doesn’t appear that anyone accepted his offers.

These messages also show how Chesebro aggressively reached out to conservative pundits and right-wing figures after Trump lost the 2020 election, prodding them to publicly promote his long-shot theories for how to subvert the Electoral College process.

The search warrants to Google and X were executed in March, shortly after CNN reported that Chesebro had concealed some of his social media accounts from prosecutors during his cooperation session last year. Chesebro has not been charged in Michigan, and he has pleaded guilty in Georgia’s election interference probe.
