Miriam Adelson, the principal owner of the NBA's Dallas Mavericks, has made a substantial $100 million donation to the Preserve America PAC in support of Donald Trump's 2024 presidential campaign. This donation has created a political rift with Mavericks minority owner Mark Cuban, a known critic of Trump who sold his controlling interest to Adelson in December 2023 but retains a 27% stake in the team. Despite their differing political views, Cuban has expressed no personal issue with Adelson's contribution. The donation marks the largest political contribution by any sports team owner in the country, with Adelson previously backing Trump during the 2020 election. Adelson's financial support for Republican causes has been significant, having donated over $100 million this year alone, including contributions to other political figures. The Adelson family, with a net worth of $32.3 billion, has a long-standing relationship with Trump, dating back to 2015.
