Anderson Cooper Says Mom Gloria Vanderbilt Couldn't Be Trusted With 'The Mole' Secrets (Flashback)

Who is ‘The Mole’?! Anderson Cooper chatted with ET about comparisons to ‘Survivor,’ and going from being a combat reporter to hosting the reality competition series in 2001. Anderson reveals at what point in the season he realized who the mole was, and calls the show a ‘cross between 'Mission: Impossible' and an Agatha Christie murder mystery.’ The future CNN anchor jokes that he couldn’t tell his mother, Gloria Vanderbilt, anything about the series, because she couldn’t ‘keep a secret to save her life.’ While the show may be celebrating its 20th anniversary, there’s still no spoilers to be found here!
