Unidentified aerial phenomena (UAP) whistleblower and former Air Force intelligence officer David Grusch accused intelligence agencies Tuesday of hiding billions of dollars in secret government spending from Congress. His investigation uncovered what he described as "slush funds" pools of money allegedly operating outside normal congressional oversight channels " worth billions of dollars annually that were allegedly used to support activities operating outside normal oversight channels, Grusch said speaking at a Capitol Hill event alongside members of the House Task Force on the Declassification of Federal Secrets. "This is also a real fraud, waste and abuse issue," Grusch said. "During my investigation, I found slush funds to the tune of billions of dollars per annum for these activities." Asked what the government knows about nonhuman intelligence, Grusch claimed the government is aware of "several" different alien species. "It's a continuum from corporeal bipedal type life to, you know, what I would consider is like sentient plasma life," Grusch said. "But there are several that this government is aware of." Federal investigators recently alleged that former CIA official David Rush used a fraudulent "special access program" as part of a scheme involving more than $40 million in gold bars and millions in government funds, drawing renewed attention to how highly restricted government programs can operate with limited outside visibility.
