Geraldo Rivera Goes From CNBC to Fox

Geraldo Rivera is quitting his prime-time talk show on CNBC to become a war correspondent for Fox News Channel, saying Thursday he couldn't bear to stay on the sidelines during a big story.

Rivera's last CNBC show after seven years will be on Nov. 16. He said he'll be leaving for Afghanistan the next day.

His legal affairs talk show is one of CNBC's highest-rated programs, although down from its heights during the O.J. Simpson trials. His 10 years as a syndicated talk show host ended in 1998.

Rivera, who exercised an exit clause in his NBC contract, said he wanted to do more reporting but it was difficult when he was committed to a talk show four nights a week.
