News Corp chairman/CEO Rupert Murdoch has hired New York City public schools communications director Natalie Ravitz to be his new chief of staff. Ravitz joined the NYC Department of Education in June 2010 under then-chancellor Joel Klein, who is now an EVP at News Corp. Before joining NYC’s education department, Ravitz was deputy chief of staff for U.S. Senator Barbara Boxer of California. News of Ravitz’s hiring comes a day after News Corp promoted Julie Henderson to SVP corporate affairs and chief communications officer. Henderson’s predecessor Teri Everett is leaving the company February 10th.
