Ex-Gen. David Petraeus, former director of America's Central Intelligence Agency, topped Barbara Walters's list of the 10 most fascinating people of 2012.
Petraeus, who resigned in disgrace after an extramarital affair with his biographer came to light, was the only person on Walters' roster to remain a secret until her TV special aired Wednesday night.
"He is, without question, one of the finest officers and military minds of his generation," Walters said. "Then shockingly, he resigned this fall as head of the CIA because he'd had an extramarital affair with Paula Broadwell, his biographer. ... The story was irresistible -- the keeper of the nation's secrets unable to conceal his own."
