Energy Executive Alan Armstrong Appointed to US Senate to Complete Mullin's Term
Republican Governor Kevin Stitt of Oklahoma has appointed energy industry veteran Alan Armstrong to serve in the United States Senate through the end of 2026, filling the vacancy created by Markwayne Mullin's promotion to Secretary of Homeland Security. Armstrong, the former chairman and CEO of pipeline operator Williams Companies, will complete the remaining nine months of Mullin's term but is legally barred from running for a full term this November under Oklahoma state law.
Conservative Business Leader Selected for Senate Role
Governor Stitt, who had promised to appoint a conservative voice to the Senate seat, described Armstrong as "a strong business leader who understands the power of free markets and limited government." The appointment comes just days after Mullin was confirmed to lead the Department of Homeland Security, a position that opened when he would have been facing reelection this autumn.
Armstrong, 63, has never held elected office but brings extensive energy sector experience to the Senate. During his career at Williams Companies, which employs approximately 5,800 people and specializes in natural gas collection, storage, and transportation, Armstrong served as president and CEO from 2011 before transitioning to executive chairman last year.
Infrastructure Permitting Reform as Top Priority
In his first statements as senator-designate, Armstrong identified streamlining infrastructure permitting as one of his primary legislative objectives. "The truth is, it's gotten very, very hard to build large-scale infrastructure, and it is so critical to our country's competitiveness in the long term," Armstrong stated, highlighting challenges facing major energy and transportation projects.
Armstrong revealed he has already met with President Donald Trump and believes his previous collaborations with Interior Secretary Doug Burgum and Energy Secretary Chris Wright helped secure presidential support. "Those gentlemen know how hard I've been working to get permitting reform done, so he was very welcoming and highly supportive," Armstrong commented about his discussion with the president.
Political Context and Immediate Reactions
The appointment occurs against a backdrop of immediate political maneuvering, with Republican Congressman Kevin Hern quickly announcing his candidacy for the Senate seat and receiving President Trump's endorsement. Meanwhile, Armstrong has been a longtime supporter of Governor Stitt, contributing the maximum $8,500 allowed under Oklahoma campaign finance laws since 2018.
Former Tulsa Mayor Dewey Bartlett, Jr., who leads an oil and gas company, praised Armstrong's selection, describing him as an "even-tempered individual" more inclined toward consensus-building than ideological rigidity. Bartlett noted Armstrong's energy market expertise is particularly valuable given global oil market disruptions related to conflicts involving Iran.
Mullin's Transition to Homeland Security Leadership
Markwayne Mullin, who previously expressed regret for calling a political opponent a "deranged individual," faced confirmation hearings last week where he positioned himself as a steady hand to lead DHS following the controversial tenure of former Secretary Kristi Noem. Noem faced significant criticism over immigration enforcement policies and mass deportation operations during her leadership.
Governor Stitt, who will leave office in January while serving as head of the National Governors Association, made the Armstrong appointment weeks after a public dispute with President Trump over attendance at the association's annual meeting. The selection represents a strategic alignment of business expertise with political priorities as Oklahoma prepares for both a Senate election and gubernatorial transition.
