Oklahoma names Williams Companies executive to temporarily fill Mullin’s Senate seat

Oklahoma Gov. Kevin Stitt selected Alan Armstrong, executive chair at Williams Companies, to fill Senator Markwayne Mullin’s seat until the November election. Armstrong has no prior public office and is barred by state law from running this fall, with Rep. Kevin Hern the clear favorite for the full term. The pick followed White House discussions, including with Trump, reflecting Oklahoma’s energy ties.
