WASHINGTON ― Attorney General William Barr told Congress on Sunday that he and Deputy Attorney General Rod Rosenstein had concluded that the evidence Robert Mueller developed during his special counsel investigation “is not sufficient to establish” that President Donald Trump committed obstruction of justice.

What Barr’s letter doesn’t mention is that less than a year ago, he’d criticized Mueller’s focus on obstruction of justice in an unsolicited 19-page memo to Justice Department officials.

Barr’s letter on Sunday said that Mueller’s report featured a “cataloguing” of the president’s actions, “many of which took place in public view.” Mueller’s report “did not draw a conclusion ― one way or the other ― as to whether” Trump obstructed justice, Barr wrote. Mueller’s report states that while it “does not conclude that the President committed a crime, it also does not exonerate him,” Barr noted.

“Generally speaking, to obtain and sustain an obstruction conviction, the government would need to prove beyond a reasonable doubt that a person, acting with corrupt intent, engaged in obstructive conduct with a sufficient nexus to a pending or contemplated proceeding,” the attorney general wrote. He said that those elements weren’t present in the Trump actions scrutinized in Mueller’s report.
