“Oklahoma Gov. Kevin Stitt (R) has appointed energy executive Alan Armstrong to represent the state in the Senate, replacing outgoing Sen. Markwayne Mullin (R), who was confirmed Monday to lead the Department of Homeland Security (DHS). … Armstrong will be asked to pledge not to run for a full term after temporarily filling the vacancy — a unique element of Oklahoma law that quickly sparked chatter around potential candidates for this fall, when Mullin was set to seek reelection.” (03/24/26)
