President Donald Trump says he's heard some interesting things about Roswell, but he's not sharing even with his eldest child. Trump made the comments Thursday in a Father's Day-themed interview with his son. Don Jr. wound down his interview by jokingly asking his Dad/President if he would ever divulge more information about Roswell, the New Mexico city known for its proximity to arguably most famous UFO event - and let us know what's really going on." Trump responded, "I won't talk to you about what I know about it, but it's very interesting." In 1947, a rancher discovered unidentifiable debris in his sheep pasture outside Roswell. Air Force officials said it was a crashed weather balloon, but skeptics questioned whether it was in fact an extraterrestrial flying saucer. Decades later the U.S. military acknowledged the debris was related to a top-secret atomic project. Still, the UFO theory has flourished. After his father offered that he heard some "interesting" things about Roswell, Trump Jr. asked [if] the president might declassify that information someday. "Well, I'll have to think about that one," the president responded.
