If you want to know why William Barr is under political attack, consider his interview last week with Jan Crawford of CBS News. It’s a humdinger, in which the Attorney General challenges the received wisdom about the investigation into Trump-Russia collusion.

Nearby we excerpt Mr. Barr’s comments about the behavior of former top FBI officials James Comey and Andrew McCabe. Note how he disagrees with President Trump’s charge of “treason.” As the AG points out, the Constitution specifically defines treason as “only in levying War against [the United States], or in adhering to their Enemies, giving them Aid and Comfort.”

But note too that Mr. Barr takes seriously the bias displayed by FBI officials against Mr. Trump. And he calls out the press for a double standard in failing to be alarmed about a potential abuse of power by law enforcement and intelligence agencies in spying on an American presidential campaign.
