Former President Donald Trump, his former chief of staff Mark Meadows, and Rudy Giuliani are unindicted co-conspirators in the Michigan attorney general's case against the state's so-called "fake electors" in the 2020 election, a state investigator revealed in court on Wednesday.

Michigan Attorney General Dana Nessel charged 16 Republicans last year with forgery and conspiracy to commit election forgery for allegedly attempting to replace Michigan's electoral votes for Joe Biden with electoral votes for Trump at the certification of the vote on Jan. 6, 2021.

During Wednesday's hearing, which was part of preliminary examinations for the so-called fake electors, Howard Shock, a special agent for the attorney general's office, also testified that former Trump attorney Jenna Ellis is also an unindicted co-conspirator.

Shock's revelation was in response to questions from Duane Silverthorn, an attorney for Michele Lundgren, one of the so-called fake electors.

"Finally, former President Donald Trump?" asked Silverthorn.

"Yes," Shock testified.

Ted Goodman, Giuliani's political adviser, said in a statement that the former New York City mayor is "proud to stand up for the countless Americans who raised legitimate concerns surrounding the 2020 U.S. Presidential Election."

"He won't be bullied or pressured into silence by highly partisan actors," the statement said.

Nessel dismissed the charges against one of the alleged fake electors in October in exchange for cooperating with the case. The state is still pursuing charges against the other 15 defendants.

All the defendants have pleaded not guilty.

Former President Donald Trump has been dubbed a co-conspirator in the scheme to claim an unearned victory in Michigan's 2020 presidential election, according to reports of testimony from an Attorney General's office investigator. Michigan prosecutors consider Trump, former chief of staff Mark Meadows and lawyer Rudy Giuliani unindicted co-conspirators in the state's false elector plot, Howard Shock, a special agent for Attorney General Dana Nessel, said in testimony reported Wednesday by The Detroit News. "That means prosecutors believe they participated, to some extent, in an alleged scheme to commit forgery by creating a false document asserting Trump had won Michigan's 16 electoral votes when Democrat Joe Biden had won them," writes reporter Craig Mauger. Shock delivered this avowal in Ingham County District Court Wednesday as Nessel seeks felony forgery charges against 16 Republican activists who signed a certificate of votes for Trump, according to the report. Duane Silverthorn, the lawyer representing elector Michele Lundgren, reportedly went through a list of people whose status as "unindicted co-conspirator" he asked Shock to confirm. Shock also affirmed Jenna Ellis and Kenneth Chesebro — two lawyers who have accepted plea deals in Fulton County District Attorney Fani Willis' election racketeering case — are also considered unindicted co-conspirators, the Detroit News reports.
