It might be that William Barr and Robert Mueller aren’t as close as they once were thought to be.

The attorney general reportedly received a letter from the special counsel that challenges the AG’s public interpretation of the report that the special counsel filed regarding the conduct of Donald Trump’s 2016 presidential campaign.

What do you know about that?

I had thought initially that we needed to hear from Mueller about what he thought of Barr’s four-page summary of the report Mueller filed with the Justice Department. Now we have. His reaction is a doozy.

Mueller wrote Barr a letter that suggests that Barr’s summary injects “confusion” into what Mueller’s team concluded about Trump’s alleged “collusion” with Russians who attacked our electoral system. Mueller’s reaction came immediately after Barr released his summary of what he said was Mueller’s conclusion.

Mueller seems to suggest that Barr sought to give the president cover from what Mueller found out.

I won’t go so far as to suggest that Barr should be resign or be impeached, as some have said should happen. I mean, he did release a redacted report to the public and it has exposed a number of questions about what Mueller determined happened during the 2016 presidential campaign.

Politico reports that Mueller’s letter has revealed a “widening rift” between the men who have been friends for decades. Politico also reports that the letter suggests that Mueller’s team is “angry” over the way Barr characterized its findings about Trump’s behavior.

I kind of expected this reaction from Mueller once Barr’s summary was released. I am surprised it took so many weeks to make it known to the public.

Mueller wrote, in part, to his (possibly soon-to-be former) friend Barr: “This threatens to undermine a central purpose for which the Department appointed the Special Counsel: to assure full confidence in the outcome of the investigations.”

The nation needs some answers from the attorney general. He is supposed to testify Thursday before the House Judiciary Committee.

My sincere hope is that he shows up, takes the oath, and answers this question truthfully: Mr. Attorney General, did you write your summary intending to cover up for the president of the United States?
