Gave over $100m with Sheldon Adelson in 2018
US Midterms 2026: Mentioned in: Texas PAC's only donor got Musk's sumsBackground
Miriam Adelson is one of the largest Republican donors in US politics, and her gifts appear on filings under her own name. In the 2018 cycle she and Sheldon Adelson gave more than $100m to Republican committees. Set against that is TEXAS PAC in 2026, a committee whose only reported donor is the Senate Leadership Fund.
A physician trained at Tel Aviv University, she worked on drug addiction at Rockefeller University and co-founded the Adelson clinics. She became the owner of Las Vegas Sands after her husband's death in 2021 and publishes the Israeli newspaper Israel Hayom. In December 2023 her family bought a controlling stake in the Dallas Mavericks; her son-in-law Patrick Dumont is the team's governor.
Her donations are the open-name benchmark at a time when outside money can reach a race through a committee that reports another committee as its donor.
