Candidate Paul assigns reading to Giuliani

Among the books on Paul's reading list were: "Dying to Win," which argues that suicide bombers only mobilize against an occupying force; "Blowback," which examines the unintended consequences of U.S. foreign policy; and the 9/11 Commission Report, which says that al Qaeda leader Osama bin Laden was angered by the presence of U.S. troops in Saudi Arabia.

Another book on the list was "Imperial Hubris," whose author appeared at the press conference to offer support for Paul.

"Foreign policy is about protecting America," said author Michael Scheuer, who used to head the CIA's bin Laden unit. "Our foreign policy is doing the opposite."

A Giuliani campaign official could not confirm whether he had read any of the books on Paul's list.
