Progressive Texas Congressmember Greg Casar has challenged his Republican counterparts to prove their commitment to workers by backing union-boosting legislation. In a social media post, Casar wrote, “If Republicans wanna talk like they’re pro-worker, then let’s have a vote on the PRO Act next week. Let’s see which politicians are for unions and which ones are all talk.” This comes as Republican vice-presidential nominee JD Vance attempts to court working-class voters, and after Teamsters President Sean O’Brien addressed the RNC Monday.

Other union leaders, meanwhile, are warning voters not to succumb to fake worker appeals by the Republican Party. AFL-CIO President Liz Shuler said, “A Trump-Vance White House is a corporate CEO’s dream and a worker’s nightmare,” while SEIU President April Verrett warned, “Vance’s loyalties lie with the Wall Street bankers and Silicon Valley billionaires who have bankrolled his political career.”
