Billionaire businessman Mark Cuban is set to join Vice President Kamala Harris in Wisconsin for campaign events in Milwaukee and La Crosse as part of her presidential campaign efforts. Cuban, who has publicly opposed Donald Trump's economic policies, endorses Harris' agenda, which aims to stimulate economic growth and support the middle class. This campaign collaboration marks Cuban's first of several planned appearances in key swing states, including future events in Arizona and Michigan. The Harris campaign emphasizes economic initiatives, including tax cuts for small businesses and first-time homebuyer assistance, to counter Trump's perceived economic strengths. Cuban's support aligns with his prior endorsements of Democratic candidates in past elections. The joint appearances are part of Harris' strategy to bolster her campaign in battleground states ahead of the upcoming election.
