The Post reports: “During Tuesday’s White House briefing, press secretary Sarah Huckabee Sanders was given an opportunity to talk about firing [special counsel Robert S. Mueller III]. But rather than play down the prospect, she answered the question and asserted that [President] Trump could, in fact, fire Mueller if he wanted to.”

Her answer should create heartburn for Republicans in Congress who insist that there is no real risk Trump will dismiss Mueller, and therefore no need for lawmakers to act to restrain Trump. That excuse is wearing thin.

Even more frightening, the New York Times reports that Trump considered firing Mueller at least twice — once in June and again in December. (Interestingly, his ire was reportedly triggered by a report that Mueller had subpoenaed records from Deutsche Bank. Trump seems particularly concerned whenever Mueller veers close to his financial affairs.)

Moreover, Sanders’s formulation is not consistent with what many members of Congress and outside legal experts have concluded. “Under the current regulations, he does not have the ability to personally fire Mueller, but the White House is right that if Trump wants to remove him, he eventually can,” former Justice Department public affairs director Matt Miller tells me. “But he will have to burn down the Justice Department to do it, and one hopes such a hostile act to the rule of law would bring about the end of his presidency.”
