He later goes on to explain that, "under long-standing Department policy, a President cannot be charged with a federal crime while he is in office. That is unconstitutional. Even if the charge is kept under seal and hidden from public view—that too is prohibited.

Charging the President with a crime was therefore not an option we could consider."
