Trump’s campaign on Thursday said they were voluntarily dropping a lawsuit contesting Michigan’s election results because election officials in Wayne County “met and declined to certify the results of the presidential election.”

In fact, Republican members of the Wayne County Board of Canvassers on Tuesday refused at first to certify the results, but then reversed themselves after a public outcry.

Detroit’s lawyers said on Thursday that the campaign included “impertinent and false language” in the filing and asked a federal judge to strike the disputed document from the case record.

Detroit’s lawyers did not request a monetary penalty, but said U.S. District Judge Janet Neff had “the authority to strike materials from the record as a sanction.”
