Teamsters exec announces challenge to O’Brien after RNC speech

International Brotherhood of Teamsters Vice President at large John Palmer announced he is mounting a challenge to current President Sean O’Brien after he gave a speech at the Republican National Convention.

In a letter, Palmer said he was officially announcing his candidacy for Teamsters national office in the 2026 election and invited all Teamsters to join him in forming an opposition slate to “send Sean O’Brien back to the truck.”

“This administration rode into power on a wave of excitement generated by our members’ desires and frustration. We were promised a more engaged leadership and a more militant union. What we have received so far is a PR blast furnace of misinformation and betrayal,” Palmer wrote in the letter, first reported by In These Times’ Kim Kelly.

Palmer also appeared to post the letter to a Teamsters Facebook group.

Of the many speeches given at the RNC this week, one of the first ones was delivered by O’Brien.

Palmer laid out several reasons why O’Brien has shown he is not fit for his leadership position, including fear of retaliation among members and failing to support members in contracts.

“This has all culminated in his presence at the anti-union, anti-worker Republican national convention, kissing the ring of a man that scabbed a picket line, failing to pay workers, discriminating against people of color as a landlord, falsely accusing five black men in New York of murder, orchestrating an insurrection against the United States, dodging the draft, and appointing Union busters from the Jones Day law firm to create the most anti-union Labor Board in history,” Palmer wrote.

Palmer argued that its “naïve to believe” that people who attended the RNC will support unions in “any way, shape, form, or manner.”

“We have successfully estranged ourselves from the rest of the labor movement through the actions of one man. Should we really go out and seek more enemies right now?” his letter said.
