From the BBC article on Scrotus ducking out of the correspondants dinner:
"Every sitting president since 1924 has attended the correspondents' dinner at least once, according to the New York Times.
They traditionally make a light-hearted speech at the annual event. Former US President Barack Obama attended eight times."
I love the fact Obama went to every one he could. I bet he'd be there this year if he could but I expect it's not 'the done thing' to invite him, particularly given the Emperor is not attending.
Loving the fact that the NY sighting of Obama showed him just loving life - the lack of stress on him right now must be so utterly wonderful (and so deserved!)
