A Michigan judge has dismissed criminal charges against 15 people who signed false certificates saying Donald Trump won the state’s electoral votes in 2020. Trump lost the state and the presidency to Joe Biden.

It’s the latest loss in prosecutors’ efforts to hold accountable people associated with Trump’s attempt to overturn his election loss.

In May, an Arizona judge sent that state’s so-called “fake elector” case back to a grand jury. The Nevada case is stuck in a jurisdictional appeal after a court dismissed the case last year. In Georgia, the Fulton County district attorney’s office is fighting to keep its prosecution alive after a court ruled that the DA’s office should be removed from the case.
