He would only have to be extradited from Florida for another state's crimes. For federal indictments, the FBI just arrest him. They don't need to involve state or local police. Actually, even at Mar-A-Lago he would have a Secret Service protection squad around him. Given a federal warrant, they would turn him over to the FBI agents.
Mar-A-Lago is on the Intracoastal waterway. In the smuggling capital of the world. There are fast boats and private jets that can have Mr. Trump anywhere he wants to be whenever he wants to be there.
If there were a god...this plague would have taken him.
If there were justice...he would already be in jail.
