Lewis looked for connections between the savings and loan company and the Clintons, and on September 2, 1992, she submitted a criminal referral to the FBI naming Bill and Hillary Clinton as witnesses in the Madison Guaranty case. Little Rock U.S. Attorney Charles A. Banks and the FBI determined that the referral lacked merit, but Lewis continued to pursue the case. From 1992 to 1994, Lewis issued several additional referrals against the Clintons and repeatedly called the U.S. Attorney's Office in Little Rock and the Justice Department regarding the case. Her referrals eventually became public knowledge, and she testified before the Senate Whitewater Committee in 1995.
