Brown figured prominently in two ways in the Whitewater controversy of the Clinton presidential administration. Brown was investigating Clinton. Brown was contacted by David Hale, a municipal judge facing indictment for fraud, then functioning as a paid informant for the FBI. Under the auspices of Citizens United, Brown issued letters to 100,000 donors to Citizens United, asking for money and saying that he had proof that President Bill Clinton had engaged "in a massive cover-up and conspiracy to obstruct justice" in the investigations surrounding the Whitewater controversy. At the same time that Brown was investigating the Clintons, he was using the tax-exempt status of Citizens United to acquire funds, urging his donors to fill out an "emergency impeachment" survey, utilizing a push-poll technique. Brown's fundraising literature said, "Our top investigator, David Bossie, is on the inside directing the probe as Special Assistant to U.S. Senator Lauch Faircloth on the U.S. Senate Whitewater Committee."
