David Corn has been an investigative journalist for more than 20 years. During the recent presidential election, Corn published the now-infamous “47 percent” video of Republican candidate Mitt Romney. Now, Corn has another secret tape: this one of Kentucky Republican Sen. Mitch McConnell. He’s heard talking about using damaging personal information against would-be candidate Ashley Judd. McConnell has called the tape an invasion of privacy, but Corn insists it was obtained legally and he won’t reveal his source. Diane talks with Mother Jones’ Washington Bureau Chief David Corn about the Romney and McConnell tapes and investigative reporting in the digital age.
