As we know, D. Trump is facing growing legal problems, and at the same time being the main republican candidate for the next presidential election, which raises an interesting question: what happens if he goes to jail?
According to a former FBI agent (source):
There's no prohibition in the Constitution for a convicted felon, even potentially one sitting in jail, from being president [...] You have to be 35 years old, you have to have been a natural-born citizen and lived in the United States for 14 years [...] Even if he's indicted and even if he's convicted, that actually doesn't stop him from running for president again.
My question is not about the legality of it, or the absurdity of the whole situation, my question is purely about the logistics/protocol of being the head of the executive branch: can the president sign documents, executive orders, be debriefed on classified materials etc. while on jail?
