William Barr is probably the best-qualified nominee for U.S. attorney general since Robert Jackson in 1940. Jackson had been solicitor general and would later serve on the Supreme Court. Mr. Barr has already served as attorney general under George H.W. Bush, as well as assistant attorney general in charge of the Office of Legal Counsel, the authoritative voice within the Justice Department on issues of law throughout the government.
Yet critics decry his nomination, or at least insist that he recuse himself from supervising special counsel Robert Mueller, because of an unsolicited memo he wrote last June to Deputy Attorney General Rod Rosenstein, who then had supervisory responsibility for the Mueller investigation, and Assistant Attorney General Steven Engel, current head of the Office of Legal Counsel. The memo criticizes one obstruction-of-justice theory that some have speculated Mr. Mueller is pursuing.
The criticisms of Mr. Barr and his memo are meritless. The 19-page document does not fault the Mueller investigation of a possible criminal connection between the Trump campaign and Russia, or even any of its secondary and tertiary prongs such as the prosecutions of Paul Manafort, Michael Cohen and George Papadopoulos. It argues forcefully that the president cannot be guilty of obstruction of justice based either on his May 2017 firing of James Comey as director of the Federal Bureau of Investigation or his purported earlier request that Mr. Comey go easy on former national security adviser Mike Flynn.
Mr. Barr’s memo acknowledges that he has no inside knowledge on the facts of the case, and that factors unknown to him may be in play, including the possibility that Mr. Mueller has an entirely different—and legitimate—obstruction theory in mind.
