Christopher Mellon
Former Deputy Assistant Secretary of Defense for Intelligence
Christopher Mellon served as Deputy Assistant Secretary of Defense for Intelligence under Presidents Clinton and George W. Bush, and as minority staff director of the Senate Select Committee on Intelligence. Few people pressing the UAP issue carry that kind of establishment record, which is exactly why his involvement gave it weight.
Mellon was instrumental in surfacing the Pentagon's UAP work. He helped route the now-famous Navy fighter-jet videos to the New York Times for its December 2017 story, and he has since argued, in op-eds and testimony, that the government should treat unexplained craft as a serious intelligence and safety question rather than a taboo.
His framing is deliberately narrow and institutional. He does not assert that the objects are extraterrestrial. He argues that the United States does not know what they are, that it should, and that the secrecy around the topic has cost it real answers. That sober, security-first posture is his signature in the debate.
