C’est une approche intéressante. Et effectivement aux USA, il y a une réponse très claire là-dessus : la section 3 du 14e amendement de la Constitution :
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.
Et elle semble être applicable dans le cas présent : WaPo - There’s an alternative to impeachment or 25th Amendment for Trump, historians say
But as calls emerged almost immediately for President Trump’s ouster and ban from office via the 25th Amendment or impeachment— neither course is expeditious or easily accomplished — Foner began pondering a different remedy provided by Section Three of the amendment,
Over the weekend, interest grew in Section Three beyond the historical realm, with at least one congresswoman broaching the strategy to bar Trump from holding federal office. House Speaker Nancy Pelosi (D-Calif.) warned Monday that the House will move forward with impeaching Trump for a second time if Vice President Pence does not seek to remove him under the 25th Amendment by tomorrow. The House could impeach Trump on a charge of “incitement of insurrection" — a reference to the 14th Amendment — as early as Wednesday.
Others want to use the 14th Amendment against members of Congress who supported the baseless allegations that the election was stolen from Trump and the demonstrations that led to the deadly attack on the Capitol.
