March 24, 2019 was the single best day of President Trump’s presidency. Of course, that was the day when Attorney General William Barr cleared the president on campaign collusion with the Russians and on obstruction of justice, the two key subjects of special counsel Robert Mueller’s nearly two-year investigation. Trump predictably claimed vindication. Addressing reporters in front of Air Force One, he declared victory over a group of people he has long regarded as deep-state, Democrat-loving bureaucrats seeking to destroy his presidency.

Trump, though, has a problem — Barr’s top-line conclusions are not the end of the story.
