Yes.
US Constitution, Fourteenth Amendment, 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.
January 6th might qualify, especially if it is proved that Trump tried to make Mike Pence reject the electors. He swore to uphold the Constitution in his oath of office, and then tried to undermine the Constitution to stay in power, breaking his oath of office. I seriously doubt that Trump can get two-thirds of each House to vote to excuse such an action.
