President Donald Trump said he has heard of “interesting” information about Roswell, New Mexico.

Trump spoke to his son Donald Trump Jr. in a special Father’s Day interview on his official YouTube channel.

“Before you leave office, will you let us know if there’s aliens? Because this is the only thing, I really want to know. I want to know what’s going on. Would you ever open up Roswell and let us know what’s going on there?” Trump Jr. asked.

“So many people ask me that question,” Trump said. “There are millions and millions of people that want to go there, that want to see it. I won’t talk to you about what I know about it, but it’s very interesting. But Roswell is a very interesting place with a lot of people that would like to know what’s going on.”

Roswell, New Mexico, is notorious for its U.F.O. sightings in 1947. The U.S. Air Force later revealed it was due to a secret nuclear test, but conspiracy theorists still believe it was U.F.O. stuffed with alien bodies that were taken to Area 51.
