This afternoon, a story by Gizmodo's Ashley Feinberg that appeared to uncover Comey's real social media accounts got a lot of attention. (Read the full story—she makes a pretty compelling case that @Projectexile7, which goes by the name Reinhold Niebuhr, and the reinholdniebuhr Instagram account, belong to the FBI director. For your info, Niebuhr was an American theologian who is known for developing the philosophy of Christian realism—while a student at the College of William and Mary, Comey wrote his senior thesis about him.)
Now, within the last hour, those accounts have responded and appear to be congratulating Feinberg for her scoop, and the tweet even includes a link to the FBI's job listings page. It's also likely that his son (whose social media activity led Feinberg to Comey's apparent accounts) is behind those posts. If not, Comey has a great sense of humor.
