"A new book by the author Ron Suskind claims that the White House ordered the CIA to forge a back-dated, handwritten letter from the head of Iraqi intelligence to Saddam Hussein.

Suskind writes in 'The Way of the World,' to be published Tuesday, that the alleged forgery -- adamantly denied by the White House -- was designed to portray a false link between Hussein’s regime and al Qaeda as a justification for the Iraq war....

'The White House had concocted a fake letter from Habbush to Saddam, backdated to July 1, 2001,' Suskind writes. 'It said that 9/11 ringleader Mohammad Atta had actually trained for his mission in Iraq -- thus showing, finally, that there was an operational link between Saddam and al Qaeda, something the Vice President's Office had been pressing CIA to prove since 9/11 as a justification to invade Iraq. There is no link.'"
