Marion Michael "Mike" Rounds is an American Republican politician born in Huron, South Dakota, on October 24, 1954, whose UAP relevance comes from Senate oversight and disclosure legislation rather than a personal witness or contactee claim.1 He served in the South Dakota state senate from 1991 to 2000, as state senate majority leader from 1995 to 2000, as South Dakota's governor from 2003 to 2011, and as a United States senator beginning with his January 6, 2015 swearing-in.12
South Dakota Offices Behind the Senate Role
Rounds entered national UAP politics with a long state-level executive and legislative record.12 The Biographical Directory of the United States Congress identifies him as an insurance and real-estate executive, South Dakota state senator, majority leader, governor, and Republican senator reelected in 2020 for a term ending January 3, 2027.1 His Senate office identifies his current committee portfolio as Appropriations, Armed Services, Banking, Housing and Urban Affairs, Indian Affairs, and the Select Committee on Intelligence.2 In the 119th Congress, Rounds also announced that he would again chair the Armed Services Subcommittee on Cybersecurity, a panel he had served as the top Republican on since its 2017 creation.3
How Rounds Entered the UAP Record
Rounds entered the UAP record through the Senate amendment process for the fiscal year 2024 National Defense Authorization Act.45 On July 13, 2023, Chuck Schumer submitted SA 797 for himself, Rounds, Marco Rubio, Kirsten Gillibrand, Todd Young, and Martin Heinrich; the text named the proposal the Unidentified Anomalous Phenomena Disclosure Act of 2023.4 The next day's Schumer-Rounds announcement framed the amendment as a way to give UAP records a presumption of disclosure, create a National Archives collection, and add a review board modeled on the JFK records law.5
Rounds said the goal was to assure credibility for investigations and records associated with UAP materials, and he argued that centralizing documents and using a reputable review board would strengthen future investigations.5
The Schumer-Rounds Architecture
SA 797 proposed a broad disclosure system.4 The amendment declared that federal UAP records should be preserved and centralized, should carry a presumption of disclosure, and should be released through an enforceable process for public disclosure.4 Its text also proposed a presidentially appointed nine-member UAP Records Review Board, standards for postponing disclosure, a controlled-disclosure process, and federal eminent domain over recovered technologies of unknown origin and biological evidence of non-human intelligence that might be controlled by private persons or entities.4
The amendment text cited "credible evidence and testimony" as Congress's basis for creating the disclosure process.4
What Congress Actually Enacted
The final fiscal year 2024 NDAA kept a narrower version of the records system and became the Disclosdex event 2024 NDAA UAP Records Collection.67 The conference report says the agreement included requirements to establish a government-wide UAP records collection, transfer records to the collection, and review records under disclosure-postponement grounds; it also says the agreement did not include the independent review board, review-board staff, eminent domain authority, or controlled-disclosure process.6 Congress.gov records that the conference report passed the Senate on December 13, 2023, passed the House on December 14, 2023, and became Public Law 118-31 on December 22, 2023.7
The National Archives later implemented the enacted mandate as Record Group 615, the Unidentified Anomalous Phenomena Records Collection.8 NARA says sections 1841-1843 of the 2024 NDAA, codified at 44 U.S.C. 2107 note, require NARA to establish the collection and require federal agencies to review, identify, and organize UAP records for disclosure and transfer.8
Floor Pushback After the Conference Loss
Rounds and Schumer used a December 13, 2023 Senate floor exchange to defend the stripped-down result while identifying what had been removed.9 Rounds said the lack of transparency had attracted public attention and compared the desired approach to the JFK records release model, while Schumer said the House had refused to work with the Senate on all important elements of the UAP Disclosure Act.9 Rounds then identified the rejected government-wide review board as a significant shortcoming and continued to frame the issue as one of public trust, records, and oversight.9
The public archive survived; the independent review board, subpoena-style review process, controlled disclosure campaign, and eminent-domain mechanism did not.69
Reintroduction After the First Fight
Rounds kept the stronger model alive after the 2023 conference result.1011 On July 11, 2024, he submitted SA 2610 to the fiscal year 2025 NDAA for himself and Schumer; the text again used the title Unidentified Anomalous Phenomena Disclosure Act, restored the review-board architecture, and defined technologies of unknown origin as physical materials or craft associated with UAP or science and technology lacking prosaic attribution or known human manufacture.10 On July 29, 2025, Schumer submitted SA 3111 to the fiscal year 2026 NDAA for himself, Rounds, and Gillibrand, again using the UAP Disclosure Act title and preserving the same basic records-disclosure architecture.11
The Congressional Record entries for the 2024 and 2025 proposals describe both as submitted amendments ordered to lie on the table.1011
Evidence Boundaries
Rounds' strongest documented UAP contribution is legislative: he helped create the Senate proposal that became a narrower National Archives mandate and then continued reintroducing the fuller disclosure architecture.4681011
The extraordinary evidentiary claims remained contested outside Rounds' personal record.12 AARO's March 2024 historical report said it found no evidence that a U.S. government investigation, academic research project, or official review panel had confirmed any UAP sighting as extraterrestrial technology, and it also said it found no empirical evidence that the U.S. government or private companies had reverse-engineered extraterrestrial technology.12
