Governor Stitt taps energy titan Alan Armstrong as Republican candidate for upcoming Senate race

OKLAHOMA CITY: Oklahoma Governor Kevin Stitt on Tuesday, March 24, appointed energy executive Alan Armstrong to the US Senate, filling the vacancy created by Senator Markwayne Mullin’s confirmation as Secretary of Homeland Security.

Announcing the move, Stitt described Armstrong as a “strong business leader,” pointing to his background in the energy sector and experience in managing large-scale operations.

Armstrong, 63, is a third-generation Oklahoman and a graduate of the University of Oklahoma. He spent nearly four decades at Tulsa-based Williams Companies, including 14 years as president and CEO before becoming executive chairman.

During his tenure, the company expanded its footprint in the natural gas industry, handling a significant share of US gas volumes.

Armstrong takes oath for short-term service

Under Oklahoma law, Armstrong is required to serve as a temporary appointee and has signed an affidavit confirming he will not run in the upcoming November election.

The provision ensures that the seat will be decided through a special election rather than an incumbency advantage.

Stitt said Armstrong’s experience in the energy sector made him a suitable interim choice. In his remarks, Armstrong said he accepted the role as an opportunity to serve the state, adding that he preferred to be involved in policymaking rather than remain on the sidelines.

Mullin confirmed as Homeland Security Secretary

The Senate vacancy followed Mullin’s confirmation as Secretary of Homeland Security. The Senate approved his nomination in a 54-45 vote on Monday, after President Donald Trump removed former Secretary Kristi Noem.

Mullin received support from two Democrats, John Fetterman and Martin Heinrich, while most Democrats and Republican Senator Rand Paul voted against the nomination.

As he transitions to lead DHS, Armstrong will join a Senate where Republicans currently hold a 53-47 majority.

Kevin Hern emerges as special election frontrunner

Attention is now shifting to the special election to fill the seat permanently. Representative Kevin Hern, who has represented Oklahoma’s 1st District since 2018, has entered the race and secured backing from President Trump.

Hern has also received support from Senate Majority Leader John Thune, strengthening his position ahead of the June 16 primary.

Stitt said he consulted with both Trump and Thune before making the appointment, noting a shared focus on energy policy and regulatory issues as key priorities for the state’s representation in Washington.
