So the story is out - Karl Rove was a source:
White House Deputy Chief of Staff Karl Rove spoke with at least one reporter about Valerie Plame's role at the CIA before she was identified as a covert agent in a newspaper column two years ago, but Rove's lawyer said yesterday that his client did not identify her by name.
Rove had a short conversation with Time magazine reporter Matthew Cooper on July 11, 2003, three days before Robert D. Novak publicly exposed Plame in a column about her husband, Joseph C. Wilson IV. Wilson had come under attack from the White House for his assertions that he found no evidence Iraq was trying to buy uranium from Niger and that he reported those findings to top administration officials. Wilson publicly accused the administration of leaking his wife's identity as a means of retaliation.
This is heavy stuff. Grand Jury, National Security violation stuff. The White House has gone silent. But there were talking before. Big game hunting season is on.
