On Sunday night's edition of "Last Week Tonight," host John Oliver skewered President Donald Trump's partially-reinstated travel ban for Muslims and his late-week Twitter meltdowns attacking the media in general and MSNBC's "Morning Joe" co-host Mike Brzezinksi in particular.


The tweets, themselves, Oliver said, were "absolutely indefensible," but White House Deputy Press Secretary Sarah Huckabee Sanders was determined to give it her best, saying that Trump has made it clear that when he's "attacked," he will always "hit back."

Oliver agreed that yes, Trump has been pretty open about that, he's pretty much "a walrus wearing a T-shirt that says, 'I have diarrhea.' He's pretty open about about how grossly shitty he can be."

"So we can really be shocked," Oliver said, "when he suddenly is."
