The last time Donald Trump attended The White House Correspondents Dinner (CSPAN, CNN, MSNOW, 8 p.m.), as a citizen in 2011, he was so severely mocked by the night’s entertainment, Seth Meyers (and to some degree by the sitting President Barack Obama) that it seemed to strengthen his resolve to run himself. After skipping the event five times, breaking the tradition of a President’s attendance since Calvin Coollidge, Trump presides today over an event that within journalism circles has been downgraded as an innapropriate co-mingling with sources.

It would seem to be even more toxic this year, given Trump’s pathological hatred of the press, the best of which has been exposing his shortcomings all along (and will be receiving awards for it tonight). At an event meant to celebrate the First Amendment presided by a person whose fervent hope is to limit it, it may make more sense that the entertainment this year will be not a comedian, but a “mentalist.” And Trump will try to tell his own jokes. It may be quite a sight.
