If Bob Novak is right, I think Fitz needs to subpoena POTUS. From the News-Observer:
Newspaper columnist Robert Novak is still not naming his source in the Valerie Plame affair, but he says he is pretty sure the name is no mystery to President Bush.
"I’m confident the president knows who the source is," Novak told a luncheon audience at the John Locke Foundation in Raleigh on Tuesday. "I’d be amazed if he doesn’t."
"So I say, ‘Don’t bug me. Don’t bug Bob Woodward. Bug the president as to whether he should reveal who the source is.’ "
