Before the Texas Legislature met in 2023, billionaire Miriam Adelson, whose family owns the Las Vegas Sands casino, dealt $3.3 million to politicians and political committees in her push to legalize gambling and allow destination casino resorts in Texas.

Pro-gaming bills gained little traction last year in the Legislature, but Adelson is going even bigger heading into the 2025 session, spreading around $13.7 million in political donations in the first 10 months of 2024.
