Markwayne Mullin, U.S. Senator from Oklahoma, posted a series of tweets on October 8, 2025, referencing a previous exchange with Sean O’Brien, President of the International Brotherhood of Teamsters, and expressing interest in collaboration between labor groups and former President Donald Trump.
In his first post, Mullin recalled a prior interaction with O’Brien during a congressional hearing, stating, “The last time @TeamsterSOB Sean O’Brien and I were in a hearing room, I was telling him to ‘stand his butt up.’ President Trump has a way of bringing people together. I’d like to see if labor can help us build in America again.” This tweet references a notable incident from November 2023 when Mullin and O’Brien had a heated exchange during a Senate hearing. Mullin, who has a background as a businessman and mixed martial artist, confronted O’Brien over comments made on social media, leading to a tense moment in the hearing room.
Later the same day, Mullin posted another tweet, “The last thing I expected.” He followed this with a third post linking to additional content, “Watch the full episode here: https://t.co/KBRKOGD5gb”.
Mullin’s references to building in America and collaboration with labor unions align with ongoing national discussions about infrastructure development and the role of organized labor. Historically, labor unions like the Teamsters have had complex relationships with both major political parties and have been key players in advocating for American workers’ rights and infrastructure investment. The mention of former President Trump in the context of bringing people together reflects broader political efforts to engage labor groups in national economic initiatives.
