Nobody has been able to verify that Luis Elizondo worked in the programs he claims to have been.
It's weird that NYT and NPR do just passive reporting and don't really verify the background this guy. He worked first for To the Stars Academy, then History Channel. Elizondo has claimed that the Government has fragments of UFOs and Aliens are thereat. I think he is just next.
Edit:
It seems Pentagon has confirmed that Elizondo did not work in AATIP, or lead it as he claims:
> “Mr. Elizondo had no responsibilities with regard to the AATIP program while he worked in OUSDI [the Office of Under Secretary of Defense for Intelligence], up until the time he resigned effective 10/4/2017.”
