The End of the Powell Era

Secretary of State Colin Powell has resigned his post but will stay on until his replacement is named. Sources say U.S. Ambassador to the United Nations John Danforth and Bush's national security adviser Condoleezza Rice are leading candidates for replacing the former four-star general.

Powell had the aura of a golden boy when he first took his post as Secretary of State. But after 9/11, Powell emerged as a lonely voice reaching out to other countries in a Bush administration ready to go it alone. While Powell publicly supported Bush, rumors boiled over that he bit his tongue while doing it.

Hear about Powell's tenure as U.S. Secretary of State and a look ahead to his possible successors.
