(Reuters) -President Donald Trump, in a speech to Israel’s parliament, spotlighted mega-donor Miriam Adelson’s outsized influence on U.S. policy toward Israel, recalling her frequent White House visits with her late husband, casino mogul Sheldon Adelson. Sheldon Adelson, who died in 2021, assembled the world's largest casino empire as head of Las Vegas Sands Corp and put much of his fortune into nurturing conservative politicians and policies in the United States and Israel. Both Adelsons have been known for their philanthropy and business ventures in Israel and donations to Jewish causes.
