Answer:
The former municipal judge that became the source of criminal allegations against the 42nd US President, Bill Clinton, was David Hale, in the Whitewater Scandal.
The Whitewater scandal was a controversy over real estate financing by Bill and Hillary Clinton at Whitewater Development Corporation, which went bankrupt in the late 1980s. A major investment by Whitewater in 1978/79 was the purchase of 200 acre of land in the Ozarks. Bill Clinton, who was Attorney General of Arkansas at the time and partnered with his wife on this land purchase, was accused in this regard of having coerced banker David Hale to grant a loan to Susan McDougal, his partner in Whitewater. The United States Securities and Exchange Commission's 1990 purchases of Whitewater Development Corporations led to the prosecution of Susan McDougal and Jim Guy Tucker, Clinton's successor as Governor of Arkansas. No proceedings have been brought against the Clintons.
