Mark McCloskey running for Senate in Missouri

Mark McCloskey, the man who attracted headlines for brandishing an AR-15 outside his St. Louis home in June 2020 as Black Lives Matter protesters marched by, is running for the open U.S. Senate seat in Missouri.

On Tuesday, McCloskey filed paperwork to run for the seat, ending speculation about his political ambitions. The St. Louis resident previously teased that a run for the seat was “a consideration.”
