LANSING — Michigan Republicans who want to oust Kristina Karamo as state party chair followed through Friday on their promise to take legal action.

Malinda Pego, who was Karamo’s co-chair and who party dissidents declared acting chair of the Michigan Republican Party when they voted to remove Karamo, sued Karamo late Friday in Kent County Circuit Court, online records show.

That means a judge may decide whether Karamo, who has been in office for nearly one year, is the rightful chair of the beleaguered state party. She has been under fire for lackluster fundraising amid allegations of autocratic rule, a lack of transparency, and improper interference in the workings of county Republican parties.

Karamo did not immediately respond to a text message seeking comment.

A group of GOP state committee members met in Commerce Township Jan. 6 and said they voted 40-5 to remove Karamo and installed Pego as acting chair. But Karamo had declared the meeting null and void even before it began, saying it was not convened in accordance with state party bylaws.

Then, on Jan. 13, Karamo called a state committee meeting in Houghton Lake, where she and others who attended said members voted 59-1 to reaffirm her position as chair. Members also voted to remove from office Pego and other dissenters.

The anti-Karamo faction is scheduled to meet in East Lansing Saturday morning to elect a permanent chair to take over from the acting chair role assumed by Pego.

Karamo’s backers mostly boycotted the Jan. 6 meeting and her opponents mostly stayed away from the meeting last Saturday. It normally takes a 75% vote to remove the state party chair, though the dissenters voted to reduce that threshold to 60% at the disputed Jan. 6 meeting.

So far, the Republican National Committee has not weighed in on either side of the dispute over the state party chair. As of Friday, the RNC still listed Karamo as chair of the Michigan Republican Party on its website.

Both Karamo’s supporters and her opponents are mostly avid backers of former President Donald Trump, who won the Iowa caucuses Monday and is the frontrunner to be the Republican nominee for president.
