Boozman agreed, alongside Tom Cotton and other Republican senators, to object to the certification of the 2021 United States Electoral College vote count. But in the wake of the 2021 storming of the United States Capitol, both Boozman and Cotton voted in support of the certification. Boozman called the attack on the Capitol "shocking and unlawful" and "a dark moment in our country's history that we must reckon with today and in the days to come."
