President Donald Trump is known for stupid/ridiculous things but John Oliver just broke it down hilariously.

Oliver this week focused on one of his favorite topics: the president. And he delivered a barrage of jokes, more specifically, the recently approved version of his “travel ban”.

“This ban is cruel, it’s unnecessary, and it undermines our standing in the world,” says Oliver in the clip. “So you would think the president would at least be justifying its existence.”

“Instead he keeps derailing the conversation with his barrage of bullshit.”

The clip’s also worth watching for Oliver’s description of Trump as “a walrus wearing a T-shirt that says ‘I have diarrhoea’” (trust us, it makes more sense when you watch the clip).
