() UFO whistleblower David Grusch has been hired as a senior adviser for Rep. Eric Burlison, R-Mo., the representative told exclusively.

Grusch’s role will mostly involve advising on issues related to unexplained anomalous phenomena (UAP), more commonly known as UFOs and will be hired for a four-month period initially.

Grusch received national attention after he claimed the Pentagon is operating a secret UAP retrieval program that has been kept hidden from lawmakers as well as the public.

His claims sparked public interest in UFOs and kicked off congressional hearings on the subject.

Other whistleblowers also came forward, with claims ranging from retrieval programs to allegations that the government has recovered not just technology from UAPs but also biological remains of nonhuman origin.

The Pentagon has repeatedly denied the existence of any such programs and has said there is no reason to believe UAPs are extraterrestrial in nature.

However, a bipartisan group of lawmakers has been vocal in pressing for more transparency.

In his role, Grusch will not work directly with the House Oversight Committee. After a request for him to be hired as committee staff, the committee rejected the proposal because of Grusch’s high profile in the press and on social media.

Grusch will only advise Burlison, who is a member of both the UAP Task Force and the committee. The House Ethics Committee approved his hiring.
