Democratic vice presidential nominee Tim Walz addressed the International Association of Firefighters (IAFF) convention in Boston, emphasizing his and Kamala Harris's commitment to labor rights and collective bargaining. Walz highlighted their support for the Protecting the Right to Organize Act, which aims to strengthen unions and protect pensions. He criticized former President Donald Trump for his 'right to work' stance, which Walz argued undermines union strength and worker protections. The IAFF, representing 350,000 firefighters and emergency workers, could be crucial in the upcoming election as both parties vie for union support. Walz's speech comes amid a series of campaign events, including a bus tour in Georgia and preparations for upcoming debates. The Republican campaign, meanwhile, is focusing on economic issues and criticizing Harris's current vice-presidential record.
