Billionaire casino owner and Republican megadonor Sheldon Adelson has died at the age of 87. Adelson was Donald Trump’s largest single donor during the 2016 race. Since 2015, Adelson donated more than $250 million to Trump, other Republicans and right-wing super PACs. He was also an influential political force in Israel, where he used his news outlets to back Prime Minister Benjamin Netanyahu and the expansion of illegal Israeli settlements in occupied Palestinian territories.
