Cable MRN 23 MEXICO 2544 (DTG 160150Z SEP 23), E.O. 13526; TAGS PGOV, PREL, ASEC, TSPA, KJUS, KCRM, MX. Released in Full by John Powers, Acting-Director, US Department of State, 2/25/2026. Signed SALAZAR. The UAP content is one of eight bullets in a routine 'Weekly Political Blotter' — most of the cable concerns Mexican domestic politics (MORENA contender selection, INE commissions, Mexico City Security Secretary, Guerrero prosecutor killings, Jalisco gubernatorial campaign) and is unrelated to UAP. Distribution included NSC, Office of the VP, DNI, CIA, DIA, USNORTHCOM, USSOUTHCOM, DHS, DOJ, Western Hemispheric posts, all US consulates in Mexico, and AMEMBASSY CARACAS. Note: corpus manifest lists incident_date as 9/12/03 but the cable is dated September 2023; manifest year appears to be a typo. Document is unredacted ('Released in Full').
The account of the hearing does not specify any tests or findings. It says the bodies’ authenticity was disputed.
No. The experts claimed the bodies were extraterrestrial, but their authenticity and connection to aliens were disputed.
It was not reported whether the bill passed. According to the account of the hearing, if approved, Mexico would become the first country to officially recognize the presence of extraterrestrial life on Earth.

At a hearing in Mexico’s Congress, experts presented bodies they claimed belonged to extraterrestrial beings. The hearing also featured videos of Mexican pilots encountering fast-moving objects in the sky.
The bodies and videos were presented during a discussion of a bill to protect the skies over the country. The bill also addressed how to recognize unidentified objects in the sky, keep air travel safe, and enable investigations. But there was no agreement about what the bodies proved, and the videos did not solve the mystery.
The experts presented the bodies as the remains of extraterrestrial beings. But their authenticity, and whether they were connected to aliens at all, became a point of dispute during the hearing. Showing them to lawmakers did not settle the debate.
The account of the hearing does not say what tests were conducted on the bodies. It provides no details about tests, findings, or how their origins were determined. So based on the available information, it is impossible to explain what fueled the dispute beyond questions about the bodies’ authenticity and the claim that they were extraterrestrial.
The experts also showed videos of encounters reported by Mexican pilots during flights. The account of the hearing says the objects appeared to be moving fast. It provides no further details about the encounters or what can be seen in the videos.
The videos and bodies were presented as part of a discussion of a bill, not as a conclusive answer to what had been seen in the sky. The experts asked lawmakers to recognize unidentified objects, protect airspace, and allow them to be investigated. According to the account of the hearing, these were goals put forward by supporters of the bill; it offers no details about any investigation or determination about the objects.
It is not known what the bodies were, what tests were conducted on them, or exactly what the videos show. It was also not reported whether the bill passed. According to the account, if approved, Mexico would become the first country to officially recognize the presence of extraterrestrial life on Earth.
The bodies were presented to Congress, but the question of what they were remains open.
