What I don’t understand is why Barr decided to take it upon himself to make a decision hastily based on “discussions with certain [DOJ] officials” when Mueller, after spending almost two years interviewing countless witnesses and reviewing many thousands of documents, had amassed evidence on both sides.

Barr’s speedy decision that Trump did not obstruct justice perhaps is not surprising. Barr wrote a 19-page single-spaced memorandum to the Deputy Attorney General and Trump’s attorneys explaining why Trump did not obstruct justice long before he become Attorney General.

As a practicing lawyer, it would take me dozens of hours to create a 19-page single-spaced memorandum containing nuanced legal analysis on any subject. I would not do so for free unless I felt very strongly about the issue. Although Barr claims otherwise in his letter, it is hard to escape the conclusion that he prejudged the matter and let his strong feelings about the subject influence his judgment.

Barr’s poor reasoning in the four-page summary will reinforce the conclusion that he prejudged the matter.
