Haim Saban, the billionaire chairman of Univision Communications, America’s largest Spanish-language media company, flew to Jerusalem in his private jet on Sept. 29 to attend the funeral of his friend Shimon Peres, Israel’s former prime minister. It was an event attended by numerous world leaders. Saban gave one of them a lift: former U.S. President Bill Clinton. In Saban’s telling, it wasn’t a big deal. “I called and asked, ‘Are you going to go?’ ” he says, recalling his conversation with Clinton. “He said, ‘Yeah, I’m going.’ I said, ‘I’m going, too. Do you need a ride?’ ” So Saban picked up Clinton and his entourage at a small airport in Teterboro, N.J.
