Michigan Attorney General Dana Nessel on Tuesday charged 16 Republicans with felony election charges in relation to their claims to be the legitimate electors of the Wolverine State during the 2020 presidential contest.

“It would be malfeasance of the greatest magnitude if my department failed to act here in the face of overwhelming evidence of an organized effort to circumvent the lawfully cast ballots of millions of Michigan voters in a presidential election,” she said.

The slate of would-be electors, Nessel contends, submitted false certificates claiming that then-President Donald Trump won the state and they were the legitimate electors, the Associated Press reported.

President Joe Biden won the battleground state, its electors, and ultimately the entire presidential contest, though Trump’s allies have contended that rampant voter fraud influenced the outcome of the contest and hold that the Republican, in fact, won.

Trump and his supporters also disputed the results in Pennsylvania, Georgia, Arizona, and Wisconsin, though they failed to secure legal wins to claim victory in any of those key battlegrounds.

The suit follows Trump’s claim to have received a target letter from special counsel Jack Smith’s office in relation to the events of Jan. 6, 2021, in which supporters of Trump entered the U.S. Capitol, demanding that Congress not certify Biden’s win.
