Former Vice President chief of staff Scooter Libby "asked a federal judge
on Monday to allow a memory expert to testify in their bid to show Libby
may have been confused or had a faulty memory in recalling conversations
in the CIA leak case."

Libby, the former chief of staff to Vice President ***** Cheney, has
pleaded not guilty, and his trial is scheduled to begin in January.
As national security advisor to Cheney, Libby's attention "was intently
focused on issues of grave importance, including domestic terrorist
threats, perilous conditions for American troops and citizens abroad and
emerging foreign policy crises," his lawyers said.

They said Bjork's testimony will show why these issues "could have easily
caused him to confuse or misremember minor details of conversations" about
Plame and her job at the CIA, topics they said Libby did not consider
significant at the time.
