Maria Shriver says she won’t resume her TV news career, citing media coverage of the late Anna Nicole Smith.

Shriver, speaking Tuesday at a women’s conference, noted the media circus surrounding Smith’s accidental drug overdose death in February.

“It was then that I knew that the TV news business had changed and so had I,” she said. “I called NBC News and told them I’m not coming back.”

Shriver took an extended leave from the network when husband Arnold Schwarzenegger ran for governor in 2003. After his victory, she made two appearances as an anchor for “Dateline NBC.”

In 2004, she announced she was leaving NBC News because she was unable to juggle her work as a journalist with her duties as California’s first lady.

Shriver’s remarks Tuesday came during the annual California Governor and First Lady’s Conference on Women. Schwarzenegger, preoccupied by the wildfires sweeping Southern California, made only a brief appearance via satellite at the conference.
