Memory issues abound in Libby CIA leak trial - Politics - MSNBC.com:

WASHINGTON - The CIA leak trial has, so far, been memorable for forgetfulness.

One by one, Special Prosecutor Patrick Fitzgerald's first three witnesses said they discussed with former White House aide I. Lewis 'Scooter' Libby the fact that a prominent Bush administration critic was married to a CIA operative.

And one by one, each witness conceded a memory problem. One could not actually remember the conversation. Another recalled it differently than when he first spoke to investigators. A third said his memory improved as time went on.
