Senate Intelligence Committee leaders and the CIA plan to ask the Justice Department to investigate who leaked a top-secret Pentagon memo to the Weekly Standard in October. The memo, which was attached to a letter sent by Undersecretary of Defense Douglas Feith to the committee, briefly described raw agency intelligence on any relationship between Iraq and al Qaeda. In making their case for invading Iraq, President Bush, Vice President Cheney and other senior administration officials initially stressed Saddam Hussein’s connection to Osama bin Laden. To date, the administration has been unable to come up with any evidence that there was a connection between the Iraqis and al Qaeda.
