Bill Clinton: I got closer to killing bin Laden

NEW YORK (CNN) -- In a contentious taped interview that aired on "Fox News Sunday," former president Bill Clinton vigorously defended his efforts as president to capture and kill al Qaeda leader Osama bin Laden.

"I got closer to killing him than anybody has gotten since. And if I were still president, we'd have more than 20,000 troops there trying to kill him," Clinton said, referring to Afghanistan.
