Governor Stitt Announces Alan Armstrong as Oklahoma’s Interim Senator

In a significant political development, Oklahoma Governor Kevin Stitt has chosen Alan Armstrong, a seasoned energy executive, to fill the U.S. Senate seat vacated by Markwayne Mullin, who was recently appointed as the Secretary of the Department of Homeland Security. The announcement was made during a press conference on Tuesday.

Alan Armstrong, currently serving as the executive chair of the Tulsa-based Williams Companies, steps into the political arena with no prior experience in public office. Governor Stitt praised Armstrong’s leadership qualities and commitment to free market principles and limited government intervention. "Alan’s story, as you guys get to know him, reflects the very best of Oklahoma,” Governor Stitt remarked. “Our values, our work ethic, and our pursuit of the American dream that is alive and well in the state of Oklahoma.”

Armstrong is set to serve in the Senate until a successor is elected in the upcoming November elections. Representative Kevin Hern (R-Okla.) is widely seen as the frontrunner to win the full term, with significant backing already in place.

Interestingly, state laws will prevent Armstrong from seeking election for the seat this fall, positioning his role as a temporary but pivotal one during a transitional period for Oklahoma politics.

The selection of Armstrong marks the culmination of a reconciliatory phase between Governor Stitt and former President Trump, who had previously clashed over various issues. The two reportedly smoothed over differences and discussed potential candidates for the Senate seat at a White House meeting, which included names like Dustin Hillary, Stitt’s former chief of staff, and oil tycoon Harold Hamm.

Armstrong expressed both humility and determination at the press conference. “This was definitely a tough decision on one hand,” he stated. “But on the other hand, it was kind of a no-brainer, because I really wouldn’t want to be sitting around in my retirement thinking, ‘gosh, I could’ve contributed and done something.’”

The decision not to run against Hern in the upcoming elections was shared by several prominent Oklahoma Republicans, including Representative Stephanie Bice and Governor Stitt himself. Hern's campaign gained a significant boost when he secured an endorsement from the president shortly after announcing his candidacy in mid-March, clearing the field ahead of the primary scheduled for June 16.

As Oklahoma navigates this period of political transition, all eyes will be on Armstrong and his approach to representing the state in the U.S. Senate, albeit for a short tenure. His background in business and leadership within the energy sector may bring fresh perspectives to the challenges facing Oklahoma and the nation at large.
