Background

After former President Donald Trump won the 2024 United States presidential election, incumbent Markwayne Mullin was rumored as a contender for U.S. Secretary of Interior. [2] Mullin's resignation would have affected the gubernatorial election, as governor Kevin Stitt would have appointed a replacement who must sign a potentially unenforceable [a] oath promising not to run for reelection in 2026. [3] Mullin was not appointed Secretary of Interior. [4]
