On May 8, 2026 — exactly 25 years after Steven Greer first brought military and government witnesses before the press at the National Press Club in Washington, D.C. — Greer returned to that same stage with a new cast of witnesses, new evidence, and a surprise guest from south of the border: Mexico’s most prominent UAP journalist, Jaime Maussan.
Together, Greer and Maussan presented the latest scientific analysis of the Buga Sphere — a metallic object recovered in Colombia in 2025 that has become one of the most discussed UAP artifacts in Latin American history — alongside testimony from four new whistleblowers, including former U.S. Green Berets and military insiders describing underground facilities, recovered materials, and encounters with advanced aerial craft.
The 25th Anniversary Disclosure Event
Greer’s original 2001 press conference is widely regarded as a turning point in the modern UAP disclosure movement. More than 20 military, government, and intelligence witnesses testified before journalists at the National Press Club about firsthand knowledge of UAP programs — a moment that predated the now-famous 2017 New York Times investigations and helped lay the groundwork for congressional hearings a decade later.
The 2026 anniversary event, announced via PR Newswire, promised first-hand whistleblower testimony alongside video, photographic evidence, and analytical findings. What set it apart from earlier Greer events was the formal inclusion of Maussan — a signal that the disclosure conversation is increasingly crossing national borders.

Maussan and the Buga Sphere: From Colombia to Mexico to Washington
The Buga Sphere entered public consciousness in March 2025, when videos of a metallic orb flying at high speed over Buga, Valle del Cauca, Colombia, went viral. Shortly afterward, the object was found on the ground and its unusual properties began attracting international attention: no seams, no welds, a surface covered in symbols from no known alphabet, and a weight that reportedly changed between measurements.
It was Maussan who arranged for the object to be transported to Mexico, where he presented it at a major press conference in June 2025 alongside U.S. Congressman Eric Burlison and attorney Daniel Sheehan. That Mexico City event established Maussan as the central figure in what has become an international investigation — one that now connects Colombia, Mexico, and the United States in a shared inquiry into a single recovered artifact.
At the May 2026 National Press Club event, the results of formal scientific testing were presented. The most striking finding: resin found within the sphere has been carbon-dated to approximately 12,560 years ago — placing its origin at the end of the last Ice Age, thousands of years before any known metallurgical civilization. X-ray analysis had previously revealed a three-layered metallic structure, with an outer shell as dense as human bone, consistent with titanium or high-grade steel.
Four New Whistleblowers
Beyond the Buga Sphere, the event featured four new firsthand witnesses. According to the National Press Club event page, speakers included former military personnel with direct accounts of underground facilities, recovered non-human materials, and encounters with advanced aerial craft. Among the witnesses were former Green Berets — a departure from the intelligence and Air Force backgrounds typical of earlier Greer-era testimony.
The inclusion of special operations soldiers, if credible, would mark a significant expansion of the known UAP witness pool into ground-based military units — suggesting that encounter reports are not limited to pilots and radar operators.
Maussan’s Role in Mexican UAP Disclosure
Jaime Maussan has been Mexico’s most prominent — and most controversial — UAP journalist for over three decades. His television program Tercer Milenio has long served as the primary vehicle for UAP coverage in Spanish-language media, and his willingness to present contested evidence has made him a polarizing figure among researchers.
His 2023 presentation of alleged “non-human” mummies before Mexico’s Congress drew international mockery when subsequent analysis suggested the specimens were not what was claimed. But his role in bringing the Buga Sphere to international attention — and his formal collaboration with Greer on a Washington stage — marks a different kind of moment: one defined less by spectacle and more by institutional engagement.
For Mexican UAP watchers, the Greer-Maussan partnership represents something significant. Mexico has its own declassified military UAP record — most famously the 2004 SEDENA footage of 16 UAPs filmed by Air Force FLIR cameras over Campeche — and a congressional tradition of taking the subject seriously. A Mexican journalist co-presenting at the U.S. National Press Club signals that Latin America is no longer watching the disclosure conversation from the sidelines.

On May 8, 2026, Steven Greer and Jaime Maussan presented updated scientific analysis of the Buga sphere alongside testimony from four new whistleblowers — including former U.S. Green Berets — who described underground facilities, recovered non-human materials, and encounters with advanced aerial craft.
Who is Jaime Maussan?
Jaime Maussan is Mexico’s most prominent UAP journalist and researcher, known for decades of television and investigative coverage of Latin American UAP cases. He was a key figure in the official release of Mexico’s 2004 Campeche military footage and appeared alongside Steven Greer at the 2026 National Press Club event.
How does the 2026 National Press Club event relate to the 2001 Disclosure Project?
The May 8, 2026 event was explicitly framed as the 25th anniversary of Steven Greer’s original Disclosure Project press conference held on May 9, 2001, where over 20 military and government witnesses testified about UAP. The 2026 event featured new witnesses and the Buga sphere as new physical evidence.
What did the whistleblowers claim at the 2026 National Press Club?
Four whistleblowers testified, including former U.S. Green Berets and military insiders. Their accounts described underground facilities housing recovered non-human materials, reverse-engineering programs, and firsthand encounters with advanced aerial craft that performed beyond known human aerospace capability.
