The Pentagon is tracking more and more UFO incidents but has yet to come across any evidence of alien activity, a Defense Department official told Congress on Wednesday.
Sean Kirkpatrick, director of the All-Domain Anomaly Resolution Office, testified that the Pentgaon is currently tracking some 650 instances of UFO sightings. Kirkpatrick made the statement during a Wednesday hearing before the Senate Armed Services Committee.
Kirkpatrick testified that many of the cases that reach his office are difficult to ever close, given a lack of verifiable information. As a result, only a "handful" of cases have been formally closed, he told lawmakers.
"I will not close a case that I cannot defend the conclusions of," Kirkpatrick said, according to Politico.
