Markwayne Mullin's interim replacement has been named by Governor Stitt and I am really certain that he will hear from us constituents to pass the Save America Act.

Oil and gas executive Alan Armstrong appointed to fill Oklahoma's open US Senate seat

Grok says...

Yes, Alan Armstrong (Tulsa-based energy executive, former CEO and current executive chairman of Williams Companies, and 👉 newly appointed U.S. Senator from Oklahoma👈) and Chris Wright (U.S. Secretary of Energy, formerly CEO of Liberty Energy) know each other professionally.
They have collaborated closely in the energy sector, particularly on permitting reform for oil and natural gas infrastructure:
Armstrong has chaired the National Petroleum Council (NPC), a federal advisory committee. Wright (as Energy Secretary) requested and received NPC reports/studies on streamlining permitting and energy infrastructure, with Armstrong leading or prominently involved in the efforts.
Armstrong has publicly credited his prior work with Wright (and Interior Secretary Doug Burgum) on permitting issues as a factor in gaining support from President Trump for his Senate appointment. He stated that "those gentlemen know how hard I've been working to get permitting reform done.". They have appeared together or been referenced in the same industry contexts, such as energy forums, NPC initiatives, and discussions on U.S. energy policy, reliability, and infrastructure bottlenecks.
Their relationship appears to be one of professional colleagues and collaborators in the U.S. energy industry and Trump administration policy circles, rather than purely personal or social. No public evidence suggests a deeper personal friendship beyond these ongoing work ties, but they clearly interact directly in high-level energy policy settings.
