The International Association of Fire Fighters (IAFF) has announced that it will not endorse any presidential candidate in the upcoming election, specifically stating it will not support Kamala Harris or Donald Trump. This decision marks a significant shift for the union, which was a key supporter of Joe Biden in the previous election cycle. The union's decision not to endorse comes as Kamala Harris faces challenges in garnering support from major labor organizations, as evidenced by similar refusals from other unions. This move reflects growing discontent and a reevaluation of candidate support within the firefighting community.
