A 13-year-old cassette tape recently recovered by Sky News reveals former President Bill Clinton admitted during remarks in Australia on Sept. 10, 2001, that he passed on an opportunity to kill terrorist leader Osama bin Laden.

Ten hours before the first plane hit the North Tower of the World Trade Center, Clinton met with some 30 Australian business leaders at a hotel in Melbourne on the nation’s southern coast. The event was sponsored by J.T. Campbell and Co. Pty. Ltd., and recorded with the former president’s permission by Michael Kroger, a Liberal Party official. Clinton fielded questions on a variety of topics, including international terrorism.
