Flipped UPDATED II

Oh..please please please please, Raw Story:

NEW YORK DAILY NEWS TO REPORT THAT SOURCES BELIEVE SOMEONE HAS FLIPPED IN WHITE HOUSE, AIDING LEAK INVESTIGATION.... DEVELOPING...

Anyone have any guesses? Ari?

UPDATE:

Everyone is settling on Ari....except here:

We'll know in a few hours what the Daily News has to say, but I predict if it's true, it's Karl Rove who flipped on Friday and gave up Cheney. Karl Rove attended most of the meetings of the White House Iraq Group and according to Raw Story's report, the flip has something to do with a source now advising that Cheney personally attended two of the meetings where Kristof's May, 2003 New York Times article and Pincus's June 2003 WaPo article on Joe Wilson were discussed. Cheney has said he didn't know about Wilson until after Wilson's July 6 op-ed appeared.

If true, it might explain the chill between Cheney and Bush lately....

UPDATE II: Here's the story...no names:

"They have got a senior cooperating witness - someone who is giving them all of that," a source who has been questioned in the leak probe told the Daily News yesterday.
