Mark McCloskey, who stood armed with an AR-15 outside of his St. Louis home to confront Black Lives Matter protesters in June 2020, said he is considering a bid for U.S. Senate in Missouri.

Running for the seat, which retiring Republican Sen. Roy Blunt will vacate in 2022, is “a consideration,” McCloskey said. A run for the Republican nomination would put him up against Missouri Attorney General Eric Schmitt and former Missouri Gov. Eric Greitens, who resigned the governorship on May 29, 2018, amid a sex scandal.
