§2383. Rebellion or insurrection Whoever incites, sets on foot, assists, or engages in any rebellion or insurrection against the authority of the United States or the laws thereof, or gives aid or comfort thereto, shall be fined under this title or imprisoned not more than ten years, or both; and shall be incapable of holding any office under the United States.
They want to cancel his second term before has has a chance to run.
What's the rush?
They are saying he is dangerous because of his Presidential powers. They are using fear to convince the public that he should be removed immediately.
