Mitt Romney's 2007 Defense Of Scooter Libby Could Come Back To Haunt Him

Mitt Romney is planning to hammer President Obama for national security leaks in a major speech today. But Romney's past defense of Scooter Libby in the Valerie Plame leak case shows he hasn't always taken a hard line against suspected leakers. Asked in two 2007 debates if Libby should have been pardoned, Romney called the investigation of Libby a "political vendetta" and "prosecutorial indiscretion."
