From Holden:

And the prominent Republican is Karen Hughes.

Speaking of Hughes, in her acclaimed book “Ten Minutes from Normal,” the former White House counselor opines about the investigation into the leak on Valerie Plame . She suspects columnist Robert D. Novak ‘s sources may have been in one of the agencies, not the White House.

“But regardless of the source, the leak compromised the confidential identity of a longtime public servant, which was wrong, and unfair to her and those who worked with her. Whoever did it should come forward and not hide behind journalistic ethics for his or her self-protection.”
