Bill Barr Quit. What Finally Spooked Him?

Attorney General William Barr has resigned with a little more than a month left in President Donald Trump’s administration. This seems to suggest that Barr thinks what happens in the next five weeks could irretrievably tarnish his legacy. If so, that’s pretty stunning, considering how much Barr has already diminished his reputation and that of the Justice Department with his pro-Trump shenanigans.

What’s the January surprise Barr wants no part of? One possibility is that Barr wants to create bureaucratic distance between himself and the president so that he can say he resigned rather than serving out his term. But this seems implausible, even for a canny bureaucratic operator like Barr, given how close he has been to the presidency. And it certainly seems at odds with the fawning tone of his resignation letter.
