Twenty-second Amendment to the United States Constitution
The amendment prohibits any individual who has been elected president twice from being elected again. Under the amendment, an individual who fills an unexpired presidential term lasting greater than two years is also prohibited from winning election as president more than once. Scholars debate whether the amendment prohibits affected individuals from succeeding to the presidency under any circumstances or whether it only applies to presidential elections.
Michael Avenatti
Avenatti has on several occasions, including in a post to Twitter, expressed interest in running for President of the United States in 2020. In a CBC TV interview published in September 2018, Avenatti said he would run in 2020 only against Trump or Pence. In an October 2018 interview with CNN, Avenatti said:I have not announced whether I'm running; I haven't made a decision. What I will say is, I'm travelling around the country; I'm very encouraged by people and their reaction to me, and a lot of people are encouraging me to run, because they think that we need a fighter; we need someone to call this president out on his conduct, and we've gotta get back to making this nation what it once was.
