A routine weekly political summary transmitted by the U.S. Embassy in Mexico City on September 16, 2023, included a line item noting that the Mexican Congress had heard testimony on "alien life" during the reporting period of September 11–15. The cable, classified at the unclassified level and released in full by Acting State Department Director John Powers on February 25, 2026, placed the congressional hearing alongside a range of domestic political developments without additional analytical commentary.
What the Cable Documents
According to the State Department dispatch, designated 23 MEXICO 2544 and addressed from the American Embassy in Mexico City to the Secretary of State in Washington, the Mexican Congress hearing on "alien life" appeared as a single bullet point in the cable's summary section, listed among items including party leadership disputes, municipal security appointments, and a gubernatorial campaign launch. The cable was transmitted on routine precedence, indicating the Embassy did not assess the hearing as requiring urgent policy attention.
The document references three prior cables — 23 MEXICO 2468, 23 MEXICO 2166, and 23 MEXICO 2346 — as context for the broader political reporting, though the content of those predecessor cables is not reproduced in the released material. The cable's subject line identifies it as "Mexico: Weekly Political Blotter, Sep 11-15," a standard Embassy reporting format. Tags assigned to the cable include PGOV (government and political affairs), PREL (external political relations), ASEC (automated security), TSPA (space and aviation), KJUS (justice), KCRM (crime), and MX (Mexico), suggesting that State Department archivists associated the document with space and aviation matters in addition to its political content.
Context: The Mexican Congressional Hearing
The hearing referenced in the cable took place in the Mexican Congress during the week of September 11–15, 2023. That session has been separately reported in press accounts as the occasion on which journalist and UAP researcher Jaime Maussan presented physical specimens he described as non-human biological entities to Mexican lawmakers — an event that received substantial international media coverage at the time. The State Department cable does not characterize the testimony beyond the phrase "alien life," and it offers no analytical judgment on the claims made during the hearing.
The inclusion of the hearing in the Embassy's weekly blotter suggests that U.S. diplomatic personnel in Mexico City regarded the congressional event as sufficiently notable to log in official reporting, while the routine cable precedence and minimal description indicate it was not assessed as a priority national security or policy matter at the time of transmission.
Document Release and Limitations
The cable was released in full, with no redactions indicated in the published text, under Executive Order 13526, which governs the classification of national security information. The release was attributed to John Powers, identified as Acting Director of the U.S. Department of State at the time of declassification on February 25, 2026.
The document as published is limited in its analytical value regarding the UAP dimension of the story. It confirms that the U.S. Embassy was aware of and formally logged the Mexican congressional hearing within days of its occurrence, but it does not reflect any follow-up assessment, interagency response, or policy position regarding the testimony or the physical specimens presented. The bulk of the cable's analytical content is devoted to Mexican domestic politics, including the internal dispute within the MORENA party over its presidential candidate selection process and a series of security and electoral appointments.
The cable's existence in the State Department's released records adds a data point to the official documentary trail surrounding the September 2023 Mexican congressional hearing, establishing that U.S. diplomatic channels captured the event contemporaneously, even if the dispatch treats it as one item among many in a busy week of Mexican political news.
