President Donald Trump said late Saturday that he would issue an executive order to require voter identification for all US elections, a continuation of his efforts to overhaul the nation’s election laws, which he has long attacked and falsely blamed for his 2020 election loss.In a post on Truth Social, Trump said, “Voter ID Must Be Part of Every Single Vote. NO EXCEPTIONS! I Will Be Doing An Executive Order To That End!!!” He did not provide further details about the order. He also reiterated his intention to restrict mail-in voting except for those who are very ill or in the military serving far away, as well as his opposition to voting machines.The announcement signals Trump’s latest effort to influence election laws using an executive order, something that he has dubious authority to do. The Constitution gives the president no explicit authority to regulate elections. Rather, it gives states the power to decide the rules of elections, oversee voting and try to prevent fraud. It gives Congress the ability to override state laws on voting. Any executive order from the president regarding elections is likely to see legal challenges.
