David Charles Grusch (born 1984, Pittsburgh): 14 years as a US intelligence officer. Air Force Major (active duty, Air National Guard, Reserve). National Geospatial-Intelligence Agency (NGA) at GS-15 civilian level — military equivalent of full-bird Colonel. NGA’s co-lead for UAP and trans-medium object analysis. Held clearances “to literally all relevant compartments” at the Pentagon. 2019-2021: National Reconnaissance Office representative to the UAP Task Force in reservist capacity. WHISTLEBLOWER CHAIN: Spent 4 years interviewing 40+ credentialed current and former military and intelligence officers who reported the existence of classified crash retrieval programs. Filed a PPD-19 Urgent Concern complaint with the Intelligence Community Inspector General (ICIG) in 2021 alleging government retaliation for his disclosures. ICIG found the complaint “credible and urgent.” JUNE 2023: First public disclosure via The Debrief (reporters Leslie Kean and Ralph Blumenthal). JULY 26, 2023 TESTIMONY (under oath, House Oversight Committee, alongside Fravor and Graves): “I was informed in the course of my official duties of a multi-decade UAP crash retrieval and reverse-engineering program to which I was denied access.” Non-human biologics: “This was the assessment of people with direct knowledge on the program I talked to, that are currently still on the program.” Rep. Burchett: “Have anyone been murdered that you know of?” Grusch: “I have to be careful asking that question.” AOC: “If you were me, where would you look?” Grusch: “I’d be happy to give you that in a closed environment.” Post-hearing: bipartisan group called for a select committee with subpoena power. ICIG Thomas Monheim conducted classified House briefing January 2024. Clearance revocation: DoD IG claimed behavioral issues; appeals panel unanimously reversed as “a mistake.” Rep. Burlison 2025: named Grusch special advisor. Garry Nolan vouches personally. Grusch: “We’re definitely not alone. The data points quite empirically.”
