Mr. President, for generations, Americans understood that building our critical infrastructure was not a partisan cause; it was a national responsibility. Previous generations built the powerplants, pipelines, highways, transmission lines, and mines that raised our standard of living, enabled the growth of our economy, protected our national security, and expanded opportunity across this country. The generations before us were builders, and their efforts gave us the great Nation we often take for granted today.
Biography
Alan Armstrong is Oklahoma’s junior U.S. senator, appointed in March 2026 after Markwayne Mullin resigned to become secretary of homeland security. A Republican, Armstrong entered the Senate without prior elected office after a long run in the energy business. He led Williams, the oil and gas company, as CEO from 2011 to 2025. That makes him a rare late-career Senate appointee whose résumé is corporate rather than legislative.
