Gardner , a Democrat, launched an investigation in January 2018 after TV station KMOV aired a report that Greitens, a married father of two, had had an affair in 2015 with his St. Louis hairdresser.
Politico recently reported that Mark McCloskey is considering running for the Senate in 2022 after Republican Sen. Roy Blunt announced in March he would not seek reelection. Greitens had already announced in March that he will seek the Republican nomination for Senate in 2022.
In a statement last June, Gardner described the encounter between the McCloskeys and the crowd as "a violent assault" against those exercising their First Amendment rights. Missouri Gov. Mike Parson, a Republican, previously called Gardner’s action toward the couple "outrageous.".
