During the Clinton administration, Conason's investigative reporting on Whitewater brought him national media attention, and he was a frequent cable television guest during Bill Clinton's impeachment trial from 1998 -1999. During this time, he also revealed the existence of the "Arkansas Project," a secret, multi-million dollar plan funded by a conservative Pittsburgh billionaire to find (or invent) negative material about the Clintons. In 2004, Conason was one of the first journalists to delve into the background and finances of the group known as the "Swift Vets and POWs for Truth".
