DETROIT (AP) — A state investigator testified Wednesday that he considers former President Donald Trump and his White House chief of staff to be uncharged co-conspirators in a scheme to claim that he had won Michigan in the 2020 election, despite Democrat Joe Biden’s clear victory.

Trump and Mark Meadows were among the names mentioned during the cross-examination of Howard Shock, whose work led to forgery charges against more than a dozen people in Michigan. A judge in the state capital is holding hearings to determine if there’s enough evidence to order a trial.

A defense attorney, Duane Silverthorn, offered a series of names and asked Shock if they were “unindicted co-conspirators,” which means they weren’t charged but could have been part of an alleged plot to put Michigan’s electoral votes in Trump’s column.

Prosecutors from the attorney general’s office didn’t object. Shock responded “yes” to Trump, Meadows, Trump attorney Rudy Giuliani and some high-ranking state Republicans.
