The hospitality workers’ union UNITE HERE has endorsed Vice President Kamala Harris, dismissing former President Donald Trump’s bid to win union support by promising to make tips tax-free. 

UNITE HERE announced it was supporting Harris on Monday, according to a press release from the organization. Touting itself as “the nation’s largest labor-led canvassing operation” and pledging to mobilize members to knock on 3.3 million doors across swing states, the labor group vowed to reach critical voters in Nevada, Arizona, Pennsylvania, Ohio, North Carolina, and Michigan.
