Rove named as a source of Plame leak

Ever heard of the National Journal? I hadn't. But look what this article in it today says:

NATIONAL JOURNAL: Iraq, Niger, And The CIA (02/02/2006): "On July 8, 2003, Libby and Miller met again. During a two-hour breakfast at the St. Regis Hotel in Washington, according to testimony Miller gave to the federal grand jury hearing evidence in the CIA leak case, Libby first told her that Plame worked for the CIA's Weapons, Intelligence, Nonproliferation, and Arms Control Office.

Around the same time, Deputy White House Chief of Staff Karl Rove and at least one other senior Bush administration official leaked information to a number of journalists about Plame's CIA employment and her role in recommending her husband for the Niger mission."

"one other senior Bush administration official" -- hmmm -- who could THAT be?
