As the sun set outside the plane window, Sessions began to wax philosophical about the rule of law. The Attorney General’s job, he said, is to tell the executive what he can and can’t do legally. Tenting his fingers beneath his chin, Sessions said he stands by his recusal from the Russia investigation: “I think I did the right thing. I don’t think the Attorney General can ask everybody else in the department to follow the rules if the Attorney General doesn’t follow them.”…

Sessions’ ultimate loyalty, he told me, is not to any man but to a principle. “Congress passes a law, judges follow the law, and nobody’s above the law, including the judges, and including the President,” he said. Yet every person of conviction makes a bargain by going to work for Trump: to wield the levers of power, to make changes you believe are for the better, you will have to make certain compromises. As many others can attest–and as Sessions may soon discover–following Trump can lead you astray.
