(NewsNation) — After an Air Force veteran came forward with information on what he claims are extraterrestrial craft recovered and kept secret by the U.S. government, House Oversight Committee Chair James Comer said he will hold a hearing on UFOs soon.

David Grusch, a former member of the National Geospatial-Intelligence Agency, spoke exclusively to investigative journalist Ross Coulthart about his time in Congress’ Unidentified Aerial Phenomena task force, recently renamed to the All-domain Anomaly Resolution Office, or AARO.

In Coulthart’s report for NewsNation, Grusch said the UAP task force was refused access to a crash retrieval program.

“These are retrieving nonhuman origin technical vehicles —call it spacecraft if you will — nonhuman exotic origin vehicles that have either landed or crashed,” Grusch said.

This includes spacecraft from quite a number of other species, according to Grusch, who alleges the U.S. government has recovered these nonhuman craft for decades.

Rep. Comer, R-Ky., said he is familiar with NewsNation’s reporting, and was interested in it as a piece of the investigation.

The Oversight Committee’s Ranking Democrat, Jamie Raskin of Maryland, said he hasn’t heard any plans about a UFO hearing, but would not be surprised if GOP members of the committee host one.

House Oversight Committee spokesman Austin Hacker issued the following statement to NewsNation: “In addition to recent claims by a whistleblower, reports continue to surface regarding unidentified aerial phenomena. The House Oversight Committee is following these UAP reports and is in the early stages of planning a hearing. The National Defense Authorization Act for 2022 created the All- Domain Anomaly Resolution Office which coordinates among the Department of Defense, the intelligence community, NASA, and other federal agencies to study UAPs. Americans, who continue to fund this federal government work, expect transparency and meaningful oversight from Congress.”

At first, NewsNation reported, Grusch thought he was being deceived — but then, people started to approach him with more information.

“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,” Grusch said.

Recently, he filed a whistleblower complaint, stating that he gave what he referred to as classified “proof” to Congress and the intelligence community inspector general.

While NewsNation has confirmed Grusch’s credentials and resume, it has not been able to see or verify his alleged proof. Grusch said he can’t show NewsNation the evidence for national security reasons.

At a press briefing on Tuesday, press secretary Karine Jean-Pierre referred questions on the report to the Department of Defense.

In a statement to NewsNation, the Pentagon said that, to date, “AARO has not discovered any verifiable information to substantiate claims that any programs regarding the possession or reverse engineering of extraterrestrial materials have existed in the past or exist currently.”

“AARO is committed to following the data and its investigation wherever it leads,” the statement said.

AARO’s historical review of records and testimonies is due to Congress by June 2024.

The group said it “welcomes the opportunity to speak with a former or current employee or contractor who believes they have information relevant to this historical review.”
