His inability to say words sometimes worries me tremendously.

He is having trouble word finding when he said, instead of United States.

These aren't words, these aren't slips of the tongue.

These are words he can't find them.

And this is happening over and over again.

Comedians joke about it, but it's not a joking matter.

I think there is a neurological issue that is not being addressed.

And if he had an MRI of his head over there, I would be very pleased because I think he needs it.

Is that something that could have happened in the two-hour time he was there?

Yes, it certainly could.

And the worry that I have is that maybe he's having small strokes.

And we had that once before in the White House when Woodrow Wilson was president.

His inability to find words is peculiar and has not been explained.

And I think one has to think of it as a possible neurological issue.
