According to Newsweek, Rove's attorney confirmed that he was Cooper's source. But the new spin is that Rove was trying to "discourage Time from publishing things that turned out to be false" [according to a source close to Rove].

So the spin keeps changing. First he didn't, then he didn't knowingly do it, and now they claim that he was trying to help.
This is classic Rove: kill a big bad news by dribbles. By the time you get to the end, it is beaten to a pulp with nothing left to go after. This is how they steal our thunder. Classic!
Learn Dems, learn.
