Gary Ginsberg, a close adviser to Rupert Murdoch for 11 years and a liaison to the Democratic Party, is leaving News Corp. Over the summer, Peter Chernin, News Corp.'s president and another close associate of the Democratic Party, also stepped down. A trend, perhaps? Ginsberg served as a lawyer to the Clinton White House and was hired as News Corp.'s director of communications in 1999. In the good graces of both Murdoch and the Clintons, Ginsberg arranged previously arranged meetings between them. He also brokered a meeting between Murdoch and Obama before the election.
