John Yoo

One of the leading conservative foreign policy minds in the country, John Yoo is a law professor at the University of California, Berkley, and visiting scholar at the American Enterprise Institute. As a deputy assistant to then-Attorney General John Ashcroft from 2001 to 2003, Yoo authored a number of legal memos arguing for unlimited presidential powers to order torture of captive suspects. Often called the "torture memos," these documents shaped Bush Administration policy for interrogating prisoners in the War on Terror and made arguments to protect officials from war crimes charges under the Geneva Conventions.
