PLAMEGATE UPDATE….Here’s the Newsweek piece about Karl Rove and Plamegate that I mentioned earlier today. There’s not really a lot there. Michael Isikoff reports that “one of [Matt] Cooper’s sources” was Karl Rove, a factoid that he sources to “two lawyers who asked not to be identified because they are representing witnesses sympathetic to the White House.” However, he doesn’t say what Rove was a source for. Rove’s lawyer confirmed to Isikoff that Rove spoke to Cooper, but added that “he did not tell any reporter that Valerie Plame worked for the CIA.”
