True. Donald Trump's eligibility to run in the 2024 U.S. presidential election is in dispute, due to his involvement in the January 6 United States Capitol attack. Trump's involvement in the attack and subsequent indictments may bar him from serving as president under the 14th Amendment to the U.S. Constitution's "insurrection clause", which disqualifies insurrectionists against the United States from holding office if they have previously taken an oath to support the Constitution.
