This was one of the many frustrating things about his Presidency. So many times he was reporting on what "someone" was saying was going on in the government. Motherfucker, you've got a big slice of the government working for you. Why don't you find out from them what's going on?
He spent a lot of his presidency watching Fox News and ignoring his briefings. Staff figured out pretty quickly that he likes pictures and compliments and tried to use those to help him get through minutes of material.
Especially since he's probably the person who said it on TV. But, to answer your question, of course the president should have a higher standard, and the people should hold him to it. For some reason this asshole is still around despite being a living parody.
