'He's a coward -- he cannot take criticism': MSNBC panel explains why Sarah Huckabee Sanders took Trump's lumps at the WHCD

Given Donald Trump's record of insulting everyone from warheroes to the entire nation of Haiti, it's been interesting to watch the fallout from the annual White House Correspondents' Dinner, at which comedian Michelle Wolf obliterated Trump and his administration in often explicit language.

On Sunday afternoon, MSNBC discussed how Trump is responsible for the "coarsening" of the national dialogue that created space for someone to get up on stage in front of the nation's elite political media and wish for a tree to fall on Kellyanne Conway.

Republican mouthpiece Jen Kerns didn't give Wolf a pass, but did blame Trump for not showing up to take his lumps, as every president has for the last 30 years.

"He should have been in the room," she said. "This year would have been the perfect year to go. We had a lot of accomplishments. Next year we might lose the House to Democrats, it'd be a terrible year to go. He should have been there and been part of the conversation."

Why wasn't he? Standup Comedian Pete Dominick had an answer.

"He's a coward," he said. "He cannot take criticism."
