what did the president know and when did he know it?

* "Karl Rove personally assured President Bush in the early fall of 2003 that he had not disclosed to anyone in the press that Valerie Plame, the wife of an administration critic, was a CIA employee... Rove also assured the president that he had not leaked any information to the media in an effort to discredit Plame's husband, former ambassador Joe Wilson. Rove also did not tell the president about his July 2003 a phone call with Time magazine reporter Matthew Cooper...
Randall Eliason, a former chief of the public corruption section for the U.S. Attorney for the District of Columbia and currently an adjunct law professor at American University, said that if Rove purposely misled the president, the FBI, or the White House press secretary, a reasonable prosecutor might construe such acts as "overt acts in furtherance of a criminal plan.""
