On Monday evening, Teamsters President Sean O’Brien made history by speaking at the Republican National Convention — the first time a Teamsters Union President has ever done so. The move, however, didn’t come without controversy. Union Vice President John Palmer called the decision “unconscionable.”
O’Brien then stirred more debate by tweeting in support of an article by Republican Senator Josh Hawley, which criticized corporate initiatives supporting diversity, equity, inclusion, and transgender workers. The situation then erupted when the official Teamsters Twitter account posted a statement condemning O’Brien’s endorsement, which was swiftly deleted.

“Unions gain nothing from endorsing the racist, misogynistic, and anti-trans politics of the far right, no matter how much people like Sen. Hawley attempt to tether such bigotry to a cynical pro-labor message. The message this sends to Teamsters of color, Teamster women, and LGBTQ Teamsters is that they are not welcome in the union unless they surrender their identity to a new kind of anti-woke unionism. You don’t unite a diverse working class by scoffing at its diversity,” said the now deleted tweet.
O’Brien’s support for Hawley’s views received swift backlash. “We get it. He promised you Secretary of Labor,” read a response by transgender writer Parker Molloy.
“If you’re a Teamster of color, are LGBTQ+, Sean O’Brien has just said he doesn’t give a fuck about you,” said the Daily Union Elections account.
“Scab,” said American journalist and labor activist Talia Jane.
O’Brien’s speech at the RNC puzzled many observers. He used the platform to advocate for unions while also praising Donald Trump, calling him “one tough SOB.” Throughout much of the speech, the applause was tepid to nonexistent. Reports even indicated that at least one audience member shouted “right to work,” reflecting anti-union sentiments in the Republican Party.
Meanwhile, other labor union leaders were critical of O’Brien’s appearance at the RNC. Liz Shuler, president of the AFL-CIO, responded, “Donald Trump and J.D. Vance are on the bosses’ side… We won’t be fooled.” These critiques were echoed by members of the International Union of Painters and Allied Trades, the International Federation of Professional and Technical Engineers, and other union leaders.
Even John Palmer, the Teamsters Vice President, weighed in: “A speaking engagement at the Republican National Convention by Teamsters President Sean O’Brien, regardless of the message, only normalizes and makes the most anti-union party and president I’ve seen in my lifetime seem palatable.”
O’Brien’s support for a senator’s explicitly anti-diversity and anti-LGBTQ+ views runs contrary to Teamsters Union’s official documents and policies. One document on the Teamsters website states, “We are pro-union and pro-equality. In keeping with the labor movement motto, ‘an injury to one is an injury to all,’ we support a strong and progressive labor movement that promotes full equality and respect for LGBTQ workers and their families.”
The Teamsters president’s participation and apparent endorsement of anti-trans and anti-queer politics from the Republican Party could signal a profound betrayal to LGBTQ+ workers, who depend on union protections for their safety and rights. As the Teamsters Union remains silent on its presidential endorsement, the stakes have never been higher for those workers impacted by Republican policies. LGBTQ+ union members are left with the question of whether or not their rights will be bartered away for political favor with a party that has repeatedly positioned itself against their very existence.

Our most important fundraising appeal of the year
December is the most critical time of year for Truthout, because our nonprofit news is funded almost entirely by individual donations from readers like you. So before you navigate away, we ask that you take just a second to support Truthout with a tax-deductible donation.
This year is a little different. We are up against a far-reaching, wide-scale attack on press freedom coming from the Trump administration. 2025 was a year of frightening censorship, news industry corporate consolidation, and worsening financial conditions for progressive nonprofits across the board.
We can only resist Trump’s agenda by cultivating a strong base of support. The right-wing mediasphere is funded comfortably by billionaire owners and venture capitalist philanthropists. At Truthout, we have you.
We’ve set an ambitious target for our year-end campaign — a goal of $230,000 to keep up our fight against authoritarianism in 2026. Please take a meaningful action in this fight: make a one-time or monthly donation to Truthout before December 31. If you have the means, please dig deep.
