Spoiler alert: He did no such thing.
Here’s a transcript of Trump’s exchange with a reporter about the story.
Q There are claims circulating on social media that Kamala Harris is not eligible to be — to run for Vice President because she was an “anchor baby,” I quote. Do you or can you definitively say whether or not Kamala Harris is eligible — legal — and meets the legal requirements to run as Vice President?
THE PRESIDENT: So, I just heard that. I heard it today that she doesn’t meet the requirements. And, by the way, the lawyer that wrote that piece is a very highly qualified, very talented lawyer. I have no idea if that’s right. I would’ve — I would have assumed the Democrats would have checked that out before she gets chosen to run for Vice President.
THE PRESIDENT: But that’s a very serious — you’re saying that — they’re saying that she doesn’t qualify because she wasn’t born in this country?
Q She was.
Q No, she was born in this country, but her parents did not — the claims say that her parents did not receive their permanent residence at that time.
THE PRESIDENT: Yeah, I don’t know about it. I just heard about it. I’ll take a look.
