I revealed in yesterday's taping of the McLaughlin Group that Time magazine's emails will reveal that Karl Rove was Matt Cooper's source. I have known this for months but didn't want to say it at a time that would risk me getting dragged into the grand jury.
McLaughlin is seen in some markets on Friday night, so some websites have picked it up, including Drudge, but I don't expect it to have much impact because McLaughlin is not considered a news show and it will be pre-empted in the big markets on Sunday because of tennis.
Since I revealed the big scoop, I have had it reconfirmed by yet another highly authoritative source. Too many people know this. It should break wide open this week. I know Newsweek is working on an 'It's Rove!' story and will probably break it tomorrow.
