Trump political adviser Jason Miller did not respond to a HuffPost query about whether Trump would waive his right to Secret Service protection if he wound up in the custody of state or federal law enforcement. One longtime Trump confidant, though, doubted that he would do that, and said he is more likely to ask for additional protection behind bars than he receives right now. “He would probably double up,” the adviser said on condition of anonymity. “It would be an interesting situation.” The statute governing the protection of former presidents does not speak to the possibility of one of them winding up behind bars, saying only that the Secret Service is “to protect” them for the duration of their lifetimes. Since the agency was assigned the task of protecting presidents in 1902, and former presidents in 1965, none has found himself under criminal investigation ― until Trump.
