A US Senator has said a whistleblower's UFO claims were "disturbing and pretty close" to classified information he's seen.

David Grusch, a former intelligence officer claimed that the US has a UFO retrieval program and "non-human craft" has been found but the Pentagon denied the bombshell claims.

Speaking to NewsNation, Grusch said that while working for the UAP task force, the group was denied access to a crash retrieval program.

“These are retrieving non-human origin technical vehicles, call it spacecraft if you will, non-human exotic origin vehicles that have either landed or crashed,” he said.

Grusch claimed that there were spacecraft from a variety of other species.

“I thought it was totally nuts and I thought at first I was being deceived, it was a ruse,” he told NewsNation.

“People started to confide in me. Approach me. I have plenty of senior, former, intelligence officers that came to me, many of which I knew almost my whole career, that confided in me that they were part of a program.

“They told me, based on their oral testimony, and they provided me documents and other proof, that there was in fact a program that the UAP Task Force was not read into,” he said.

Meanwhile, the Pentagon has released a statement denying the claims.
