Jay Rosen has a great take on Novak. He clearly highlights the 6/29 Ed Henry segment on "Inside Politics" which I felt was an important piece of information also. ( Of course Jay does a wonderful job of analyzing it )
The NY Times follows up with the Rove-Novak 92' connection: "In 1992 in an incident well known in Texas, Mr. Rove was fired from the state campaign to re-elect the first President Bush on suspicions that Mr. Rove had leaked damaging information to Mr. Novak about Robert Mosbacher Jr., the campaign manager and the son of a former commerce secretary."
The article describes their friendship through the years and shows how leaking information is nothing new for Karl.
