Sean O’Brien, the president of the International Brotherhood of Teamsters, made history as the first Teamster to speak at the Republican National Convention, emphasizing the union's independence from party affiliations. O’Brien's speech focused on bipartisan collaboration for American workers, critiquing big corporations and Washington's neglect of workers' interests. His address, which received a standing ovation from former President Donald Trump, highlighted the union's non-partisan stance and commitment to worker-centric agendas. Despite some backlash and controversy within the union and among Democrats, O’Brien's appearance underscored the Teamsters' willingness to engage with both political parties and prioritize workers' needs over traditional party lines.
