Miriam Adelson, owner of the holding company that controls the Dallas Mavericks, donated an estimated $100 million to Donald Trump's presidential campaign, surpassing other notable donors. Her support may indicate the Adelson family's interest in legalizing gambling in Texas. Adelson, one of the richest women in the world with a net worth of over $35 billion, is the wife of the late tycoon Sheldon Adelson, who made billions through gambling ventures. The bond between the Adelsons and Trump dates back to 2020, with Miriam Adelson donating a total of $100 million in the 2024 presidential campaign.
