"Trump is making his intentions perfectly clear. He wants the Department of Justice to lock up his political opponents and witnesses to his misbehavior. And he wants it to stop investigating his own misdeeds. The Department of Justice is constructed around restraints designed to prevent any such interference, because the power to use federal law enforcement as a weapon to protect the president and his party, and to harass the opposition, is so terrifying it has to be prevented at all costs. Trump is, on national television, making existential threats to the rule of law."
