Casino mogul and prominent Republican donor Sheldon Adelson testified Friday he isn’t sure where he was when he and his second-in-command at the time crafted a list of reasons to fire Sands China’s chief executive in 2010. Adelson, CEO of Las Vegas Sands and one of the world’s richest men, told a Clark County courtroom he could have been in a plane flying over the Pacific Ocean or at any of his homes in Southern California, Israel, Boston or Las Vegas.
