interesting commentary in Wikipedia entry - "debunked":

Several weeks after the November 2020 presidential election, Gosar and Representative Andy Biggs appeared in a video produced by the Arizona Republican Party claiming that there was widespread voter fraud in the 2020 presidential election. Gosar claims Arizona's voting machines were faulty and that Wisconsin intentionally paused counting votes to "dump" 100,000 votes into the count for Joe Biden. He also claims that deceased people voted in Pennsylvania. All of Gosar's allegations have been debunked.
