Oklahoma governor's expected pick for Mullin's Senate seat donated thousands to Adam Kinzinger
Oklahoma Gov. Kevin Stitt is reportedly preparing to appoint Alan Armstrong, an oil and gas executive based in Tulsa, to temporarily fill Sen. Markwayne Mullin's Senate seat once it becomes vacant.
Armstrong is the executive chairman of the board of directors at Williams, a major energy company. He is not a household name in Oklahoma politics, and his most notable political footprint may be the one that raises the most questions.
According to media reports citing Federal Election Commission records, Armstrong made two donations totaling $5,800 to former Republican Illinois Rep. Adam Kinzinger on March 22, 2021. That was just two months after Kinzinger voted to impeach President Donald Trump over his purported role in the Jan. 6, 2021, riot at the U.S. Capitol.
Kinzinger has since emerged as a prominent detractor of the president. He spoke at the 2024 Democratic National Convention in support of failed presidential candidate Kamala Harris, the Daily Caller reported.
That is the political record of the man reportedly next in line for a Republican Senate seat.
How We Got Here
The seat opens because Trump nominated Mullin, the junior Republican senator of the Sooner State, to replace DHS Secretary Kristi Noem. The Senate advanced Mullin's nomination Sunday afternoon and is likely to vote to confirm him either Monday or Tuesday.
NOTUS first reported the news late Saturday, citing three anonymous sources, that Stitt had selected Armstrong to succeed Mullin. KOTV-DT independently reported the same expectation Sunday morning, also citing multiple anonymous sources. NOTUS initially reported that Stitt might ultimately decide to appoint someone else after meeting with Trump at his Mar-a-Lago residence on Sunday.
NOTUS's Reese Gorman wrote Sunday evening on X that the meeting "went well," and that Stitt's official announcement is expected after the Senate confirms Mullin.
The Kinzinger Problem
There is nothing inherently disqualifying about being an energy executive. Armstrong's company bio describes a career spanning more than 30 years at Williams, where he leads nearly 5,000 employees and oversees operations that handle 30% of the natural gas used daily in the United States. That is a serious resume for a serious industry.
But a Senate appointment is not a corporate promotion. It is a political act with political consequences, and the political question here is straightforward: Why did Armstrong write checks to Adam Kinzinger weeks after Kinzinger crossed the most consequential line in Republican politics?
Kinzinger didn't just vote to impeach a sitting Republican president. He made it his brand. He parlayed that vote into cable news stardom, a seat on the January 6th committee, and ultimately a speaking slot at the Democratic National Convention. The trajectory from impeachment vote to endorsing Kamala Harris was not a surprise to anyone paying attention in March 2021. It was already visible. Armstrong donated anyway.
Donors are not candidates. People give money for all kinds of reasons, and $5,800 is not a fortune in political fundraising. But when a governor reaches past elected officials, past party activists, past anyone with a public conservative record, and selects someone whose only notable political contribution went to a man who became one of the GOP's loudest internal critics, the choice invites scrutiny.
A Temporary Seat With Permanent Implications
Oklahoma state law stipulates that Stitt's pick can only serve until the end of Mullin's term in January 2027. Trump-endorsed Republican Rep. Kevin Hern is described as the heavy favorite in the state's November Senate election. So this appointment is, in theory, a placeholder.
In practice, temporary senators still vote. They still shape floor dynamics, committee assignments, and the razor-thin margins that define what the Senate can accomplish. Every Republican seat matters. Every Republican vote matters. Appointing someone with no public conservative track record and a documented willingness to fund anti-Trump Republicans is a gamble that Oklahoma's conservative voters did not ask for.
Stitt had options. Oklahoma is one of the reddest states in the country, with no shortage of proven conservatives who would have brought both credibility and enthusiasm to the seat. Instead, the governor appears to have chosen an unknown quantity from the corporate world whose one visible act of political engagement pointed in exactly the wrong direction.
What Comes Next
The Senate confirmation of Mullin appears imminent. Once that vote clears, Stitt is expected to make his announcement official. The Armstrong appointment, if it holds, will be brief. Hern's path to winning the November election in deep-red Oklahoma is wide open.
But the choice still matters. Not because Armstrong will reshape the Senate in eighteen months, but because of what it signals. Republican governors in solidly Republican states do not need to play it safe with inoffensive corporate picks. They can reward loyalty, elevate talent, and send a message about what the party values.
Stitt chose to send a different message. Oklahoma voters will remember which one.
