Sen. Alan Armstrong has disclosed 236 buys and 29 sales since Mar 2026

Alan Stuart Armstrong is a Republican U.S. senator from Oklahoma, appointed in March 2026 by Governor Kevin Stitt to fill the vacancy created when Senator Markwayne Mullin became Secretary of Homeland Security.( A fourth-generation member of an Oklahoma oil-and-gas family, Armstrong was born in McLennan County, Texas, in 1962, raised in Bartlesville, and earned a B.S. in civil engineering from the University of Oklahoma in 1985 before joining Tulsa-based Williams Companies as an engineer in 1986.( He rose through the firm to become president and CEO from 2011 to 2025 and then executive chairman in 2025–2026, roles that made him one of the most prominent energy executives in the state prior to his Senate appointment.( Armstrong has also held leadership positions beyond Williams, including chairing the National Petroleum Council, serving as a founding member of Natural Allies for a Clean Energy Future, chairing the Board of Trustees of the University of Oklahoma Foundation, and chairing Junior Achievement USA.(

Armstrong entered the Senate with no prior elected office, bringing a corporate and energy-focused résumé to his role as Oklahoma’s junior senator.( As of mid-2026, he serves in the 119th Congress, though detailed public records of his committee assignments, specific sponsored legislation, and any notable controversies or public attention related to his personal stock trading under the STOCK Act—including trades in securities such as RDSMY, NGLOY, MT, GOOGL, and DWAHY—are not available in the current open-source congressional, financial-disclosure, or news databases consulted.( Existing profiles emphasize his background in energy infrastructure and corporate governance rather than a distinct legislative portfolio, and none of the sources reviewed document STOCK Act-related investigations, media scrutiny, or ethics complaints tied to his trading activity.( Accordingly, any claim of specific committee assignments, particular bills authored, or STOCK Act controversy would go beyond the available record and cannot be reliably substantiated at this time.(
