If you want to get a flavor of Donald Trump's latest speech made to Republicans on Tuesday, just watch the 57-second montage in the Jimmy Kimmel Live! video above — which is so all-over-the-place it's difficult to summarise in words.

"I feel like even he knows what he's saying's nuts, because just about every time he goes off on these tangents, he then makes it clear that he isn't actually scatterbrained, it's just a 'weave,'" says host Jimmy Kimmel. He then cuts back to the U.S. president explaining the importance of returning to an original point after going off on tangents so that you're "in good shape."

"That's right," says Kimmel. "No one is in better shape than he is."
