Former Dateline NBC co-anchor Maria Shriver, who is married to California Gov. Arnold Schwarzenegger, said Tuesday that she does not intend to resume her career as a television journalist. According to an Associated Press report published on Thursday, Shriver told a conference on women in Long Beach, CA that she made her decision after watching coverage of the late Anna Nicole Smith's drug-related death. "It was then that I knew that the TV news business had changed and so had I," Shriver said. "I called NBC News and told them I'm not coming back."
