Attempts to overturn the 2020 election
Trump engaged in attempts to overturn the 2020 United States presidential election, threatening Republican lawmakers who did not help his father overturn the election.[105] In November 2020 he advocated "total war" instead of completion of vote counting in the 2020 United States elections.[10] Together with his father he incited the mob that attacked the United States Capitol on January 6, 2021, forcing Congress to suspend its proceedings and evacuate. Joe Scarborough called for the arrest of Trump for insurrection against the United States.[11]
