White House reveals where it now stands on possible existence of aliens: ‘We don’t know’

The White House said Wednesday it doesn't know whether aliens exist, but would continue to investigate the numerous sightings of unidentified aerial phenomena.

Kirby said he didn't have a position on it "one way or the other" that he could immediately speak to, but did say the government believed "there are unexplained aerial phenomena that have been sighted and reported by pilots, Navy and Air Force, that these phenomena have in some cases had an impact on our training ranges, on our pilots' ability to fly, train, operate and stay ready."  Brandon Gillespie is an associate editor at Fox News.

"That alone makes it a national security issue worth looking at," he added. "Unidentified aerial phenomena doesn't exactly roll off the tongue, but it's an honest assessment of what we think about this problem set. And so we'll see where it goes."
