Matthew Brown Exposes "Immaculate Constellation" UAP Tracking Program

The available information indicates that Matthew Brown, identified as a U.S. National Security and policy analyst, allegedly came forward in 2025 as a whistleblower. He claims to have exposed a program named "Immaculate Constellation," described as a special access program focused on tracking unidentified anomalous phenomena (UAPs). Brown reportedly seeks immunity from former President Donald Trump to disclose further details about his knowledge of UFOs/UAPs to the public. However, the claims are primarily circulated through social media posts and lack independent verification or corroboration from official sources. The information remains speculative and should be considered as attributed claims rather than established facts.
