In particular, section 3 of the 14th amendment reads:
No person shall be a Senator or Representative in Congress, or elector of President and Vice President, or hold any office, civil or military, under the United States, or under any state, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any state legislature, or as an executive or judicial officer of any state, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. But Congress may by a vote of two-thirds of each House, remove such disability.
This was passed after the civil war as a means of ensuring that confederates weren't allowed to hold office.
There are modern examples as a result of the Jan. 6 2021 insurrection as well.
Yeep, I think everyone with half a brain feared for the peaceful transfer of power early in his presidency, or even back during his first campaign. Reporters asked him every now and then if he'd accept the results and he always answered wannabe-dictator shit. Then to the leading to the 6th of jan it was plain as day that he would pull something with the mail-in bailots as a justification to overthrow the government. Then of course it fucking happens, and a third of the country is playing dumb. If you were reading the alt-right popular forum you knew it was meant to be their big day, a lot of people were armed that day but they pussied out
