I remember W. doing that, and Obama joking about sending predator drones to destroy some musical group that Sasha and Malia were infatuated with. Then there was the comedienne who ridiculed Sarah Sanders for her looks; Sanders sat and took it.
W. joked about WMD, Obama joked about predator drones, some comic made fun of Sarah Sanders' appearance. The correspondent's dinner used to be a venue for people to lay off the partisanship for an evening and laugh with each other, no more, there's been a complete collapse of manners in DC. I respected Trump for refusing to attend.
