Section 3.
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.
It has already been ruled Trump engaged in insurrection.
SCOTUS has already ruled that Congress has the sole ability to enforce Section 3.
Trump is plainly ineligible for any public office of the United States of America, absent 2/3rds of Congress voting to allow him to hold the office again.
