Braun announced he planned to oppose the certification of the Electoral College vote count on January 6, 2021. He was participating in the certification when Trump supporters stormed the U.S. Capitol. In the wake of the attack, he tweeted, "Though I will continue to push for a thorough investigation into the election irregularities many Hoosiers are concerned with as my objection was intended, I have withdrawn that objection and will vote to get this ugly day behind us." He voted to support the certification after Congress returned to session. The "South Bend Tribune" called Braun's flip-flop "a case of too little, too late." The Democratic Party of Indiana called for Braun's resignation, saying he “incited violence to overturn the presidential election and end American democracy.”
