During the last Democrat debate, Hillary Clinton and Barack Obama got into a tussle over, on the one hand Hillary having worked in the Wal-Mart board of directors, and on the other hand, Obama’s 17-year relationship to Tony Rezko. Rezko is about to stand trial for fraud. Well, a photo of Hillary and Bill Clinton with Rezko has surfaced. Matt Lauer confronted Hillary Clinton with the photo this morning.

She says she hasn’t had any relationship with Rezko…but Bill infamously claimed not to have had sexual relations with that woman. There’s no reason anyone should take the Clintons at their word. One photo is not a big deal; presidents end up posing for photo ops with all sorts of people with whom they don’t have any actual relationship. But if it turns out that the Clintons have accepted campaign cash from Rezko in the current campaign or have had any relationship with him in the past, it will be a big deal.

Update (AP): Would Hillary have brought up Rezko at the debate (and allegedly told Edwards there’s more to come about him and Obama) if she knew her hands were dirty, though? Her team must have researched this.
