(CNN) President Donald Trump fired his FBI director, in part, for being a "showboat," which didn't ring true given James Comey's reputation as a standup G-Man and his commitment, even in the midst of his own political peril, for antagonizing both sides of the aisle.

Showboat or not, he's certainly shown himself to be master of the Twitter tease. But teasing what? It's not clear. He could just be messing with us.

Witness: Comey is "Reinhold Niebuhr." This we now know for sure after the former FBI director capped off a series of cryptic tweets with a photo of himself from the account that has long been suspected as his nom de plume.

The world has suspected that the Reinhold Niebuhr account, now with the handle @FormerBu, was Comey since the end of March, before he was fired, when Gizmodo writer Ashley Feinberg published a rather incredible bit of Internet sleuthing/snooping/stalking that tied the account to him. (Note: When Feinberg wrote her story, the account handle was @projectexile7 but has since been changed to @FormerBu.) The Reinhold Niebuhr name has stayed constant, however. Niebuhr, an American theologian, was a subject of Comey's college thesis.

Regardless, the messages Comey has tweeted over the past few days to emerge, unmasked, as Reinhold Niebuhr are bizarre and interesting.
