Donald Trump catches Anderson Cooper off guard with this statement: "Isn't Ted's real name Raphael? I think so, right?"

Rafael Edward Cruz.

ANDERSON COOPER, CNN: You just welcomed a new grandson...

DONALD TRUMP: ... And I really appreciate your statement. Thank you.

COOPER: You just welcomed a new grandson...

TRUMP: I did.

COOPER: His name is Theodore. Any chance you're going to call him Crying Ted?

TRUMP: No, I don't think so.

(LAUGHTER)

TRUMP: I said -- well, actually, isn't Ted's real name Raphael? I think so, right? Because that was one of the questions did have to ask.

COOPER: I -- it is.

TRUMP: I doesn't matter.

Theodore Roosevelt is somebody Jared and Ivanka have long studied and respected, and it's Theodore James. Tough, strong, and it's Theodore James, and that's what they really had in mind.
