what happened in maui?

this is a joke from America's sweatheart

i am not from the us but there's joke about him not planning to visit neither kabul nor maui (at first it was because it's a vacation destination) and then he said, and now "neither i guess" he said.

i don't want to say too much of a joke because maybe there's a copyright issue but i just wanted to know why isn't he visiting mau, at first i thought it was because of the basketball player but i found out he is from another city
