Brooks was the first member of Congress to announce his objection to the January 6, 2021 certification of the Electoral College results. In December he organized a series of White House meetings between Trump and a dozen Republican lawmakers to strategize about how to overturn the election results on January 6. On that date, he was the first speaker at a pro-Trump rally. In the speech he harshly criticized other Republicans in Congress for not aiding him in his efforts to overturn the election and said, "Today is the day American patriots start taking down names and kicking ass." At the rally Trump gave an hourlong speech claiming that the election had been stolen and urging people to go to the U.S. Capitol. The crowd did so, and shortly thereafter, pro-Trump protesters stormed the Capitol. Later that night, Congress reassembled to certify the Electoral College vote; Brooks raised an objection to Nevada's votes, but it did not succeed because no senator joined him in objecting. Brooks later said the rioters who stormed the Capitol were associated with Antifa, citing a "Washington Times" report that was later retracted.
