The Debrief published an article making several claims

, including on the existence "deeply covert programs that he says possess retrieved intact and partially intact craft of non-human origin."

A former intelligence official turned whistleblower has given Congress and the Intelligence Community Inspector General extensive classified information about deeply covert programs that he says possess retrieved intact and partially intact craft of non-human origin. The information, he says, has been illegally withheld from Congress, and he filed a complaint alleging that he suffered illegal

retaliation for his confidential disclosures, reported here for the first time. Other intelligence officials, both active and retired, with knowledge of these programs through their work in various agencies, have independently provided similar, corroborating information, both on and off the record.

This market resolves to YES if the US government has substantively confirmed the claims in the paragraph above by the end of the year, most notably that they do indeed posess intact crafts they believe to be of non-human origin. 

Confirmation must come from a source credibly speaking on behalf of the US government. A whistleblower whose claims are denied or ignored would not count.
