“I love Harrison Ford – and not just because he rents my properties. He stood up for America,” the billionaire real estate mogul and GOP presidential frontrunner recently told The New York Times of Ford’s character.

In an interview with the Studio 10 morning show, a semi-serious Ford shot back.

Asked about Trump running for president, Ford smirked and said, “It’s president! Oh, I thought it was resident. So he’s not only going to live there, he’s going to run the show”?

On being lauded by Trump for “standing up for America” in Air Force One, Ford looked straight into the camera and added, “It’s a movie. Donald, it was a movie!

“It’s not like this in real life. But how would you know?”

The snippet of Ford’s interview has been viewed hundreds of thousands of times on YouTube.

It came amid national and international furore over Trump’s controversial plan to ban Muslims from entering the United States.
