This isn't necessarily a game-changer, but with New Jersey's Democratic Governor Jon Corzine already narrowing his deficit against Republican Chris Christie, this news isn't likely to make the GOP too happy.

Former White House Deputy Chief of Staff Karl Rove says he spoke with then-U.S. Attorney Christopher Christie about his interest in running for Governor, according to testimony Rove gave to the House Judiciary Committee last month.

"I talked to him twice in the last couple of years, perhaps one time while I was at the White House and once or twice since I left the White House, but -- not regarding his duties as U.S. Attorney, but regarding his interest in running for Governor, and he asked me questions about who -- who were good people that knew about running for Governor that he could talk to," Rove told the panel.

Rove said he "vaguely" recalls Christie looking into allegations against U.S. Sen. Robert Menendez (D-Hoboken) before the 2006 election, but testified that he had no personal communications with Christie or anyone at the Department of Justice or the White House Counsel's office about the Menendez investigation.

Asked if the timing of the investigation was favorable to Republicans in the election, Rove said "I suspect so."

Christie is running as a tough-on-corruption prosecutor, the type of Republican voters in the traditionally Democratic New Jersey could support. So to the extent that this document release undercuts that image -- as it appears to, with Rove both indicating that Christie viewed the post as a stepping stone and that he also used the post to pursue political investigations -- it creates an opening Corzine to portray Christie as just another Republican.
