Are you talking about "Crisis of Character" (Byrne)?  Or perhaps "The Truth About Hillary: What She Knew, When She Knew It, and How Far She'll Go to Become President" (Klein)?   

Then again, maybe "The First Family Detail: Secret Service Agents Reveal the Hidden Lives of the Presidents" (Kessler)"

Or "Unlimited Access: An FBI Agent Inside the Clinton White House" (Aldrich)?
