The never-ending tension between Donald Trump and Jeff Sessions isn’t entirely the fault of one or the other.
Trump has a perfectly legitimate complaint about Sessions recusing himself from the Russia investigation only after being appointed. Despite the conventional wisdom of Washington, Sessions did not need to recuse himself over a few innocuous meetings he had with Russian diplomats while he was still a senator. The fact that he has done so has made him a weak leader at the Justice Department. It’s essentially given Rod Rosenstein the run of the place, and Rosenstein seems more concerned with keeping documents out of the hands of Congress than he is with seeking real justice in any matter whatsoever.
