A UFO whistleblower has claimed that a missing Air Force general was a 'hostile witness' who refused to disclose top secret information to Congress before his disappearance. 

Air Force veteran David Grusch, this week, specifically named retired Air Force General William Neil McCasland as one of the officers who had been in charge of classified programs related to non-human craft recovery and reverse-engineering.

However, Grusch alleged that the general, who vanished without a trace on February 27, had not been cooperative with lawmakers seeking to interview individuals with knowledge of America's alleged contact with extraterrestrials. 

Grusch, who is now an advisor to Missouri Congressman Eric Burlison, became a whistleblower and testified before Congress in 2023, after allegedly learning that elements of the government had been hiding UFO retrieval and reverse-engineering programs for decades.

He added that forces within the US government are still working to cover up the Trump Administration's attempt to reveal all files related to UFOs and the search for alien life.

The former intelligence officer recommended that Congress start issuing subpoenas to current and former members of the government or military who had refused to testify as the White House's push for full UFO disclosure draws closer.

Grusch said: 'They already have the list of some of these hostile folks that ran those programs. Unfortunately, one of those individuals, Major General retired Neil McCasland, is currently missing, which is very concerning to me as well.'

Using the authority from classified laws passed by Congress, Grusch explained that he had been tasked by lawmakers to interview dozens of credible military and intelligence officials ahead of UFO disclosure.

The whistleblower told Chris Farrell on Judicial Watch that about 40 people have been helpful, with roughly a dozen giving sworn testimony on classified projects to the Intelligence Community Inspector General (ICIG).

Grusch described these fellow whistleblowers as witnesses with firsthand knowledge who either 'touched' potentially non-human materials or had been inside the top-secret facilities where they were being kept.

However, he also revealed that McCasland was on a list of potential witnesses who had been labeled as 'hostile' because of their reluctance or active resistance to sharing information on alleged UFO research.

The missing general reportedly had ties to both nuclear and UFO-related government programs, overseeing operations for the Air Force Research Lab at both Wright-Patterson Air Force Base in Ohio and Kirtland Air Force Base in New Mexico.

Wright-Patterson has been tied to rumors of secret UFO projects for decades, with former government scientists alleging that debris from an alien spacecraft that allegedly crashed in Roswell, New Mexico was taken to this base for analysis.

Just eight days after President Trump publicly ordered the Pentagon to release all files on UFO activity, McCasland walked out of his New Mexico home with only a handgun and has not been seen since.

The 68-year-old left behind his phone, wearable devices and even his prescription glasses and was last seen near Quail Run Court NE in Albuquerque.

McCasland's wife, Susan Wilkerson, said she does not believe there was any foul play involved in her husband's disappearance, but also told 911 dispatchers it appeared the general 'had planned not to be found.'

Local police have not had any updates in the case, leading officials in Washington to call for an FBI investigation into McCasland's disappearance as well as a string of missing person cases involving nuclear lab employees and NASA scientists who all had ties to the general's work.

Meanwhile, Grusch claimed that more government officials were still allegedly involved in derailing the public disclosure of the nation's UFO files.

'I see a lot of power plays, a lot of games, a lot of positioning. Certain agencies are moving people into positions to kind of control the information release,' Grusch revealed.

Despite the actions he referred to as 'shenanigans,' Grusch said he believed UFO disclosure would reach a tipping point within the next 60 to 90 days.

He did not believe this first wave of documents detailing the government's connection to UFO encounters would include video evidence of alien life, but added that the files would likely confirm what whistleblowers have revealed.

'I certainly know what Congress is doing, and I won't reveal that here, but I do see a lot of pressure to get the substantive empirical holdings that I've talked about, not videos or anything like that, out in the ether.'
