A federal judge has ruled that CIA officials committed fraud to protect a former covert agent against an eavesdropping lawsuit and is considering sanctioning as many as six who worked at the agency, including former CIA Director George Tenet. According to court documents unsealed Monday, U.S. District Judge Royce Lamberth referred a CIA attorney, Jeffrey Yeates, for discipline. Lamberth also denied the CIA's renewed efforts under the Obama administration to keep the case secret because of what he calls the agency's diminished credibility" in the case. The eavesdropping lawsuit was brought by a former agent with the Drug Enforcement Agency, Richard Horn, who says his home in Rangoon, Burma, was illegally wiretapped by the CIA in 1993. He says Arthur Brown, the former CIA station chief in Burma, and Franklin Huddle Jr., the chief of mission at the U.S. Embassy in Burma, were trying to get him relocated because they disagreed with his work with Burmese officials on the country's drug trade. Horn sued Brown and Huddle in 1994, seeking damages for violations of his civil rights because of the alleged wiretapping. Tenet filed an affidavit in 2000 asking that the case against Brown be dismissed because he was a covert agent whose identity must not be revealed in court. Lamberth granted the CIA's request and threw out the case against Brown in 2004. But Lamberth found out last year that Brown's cover had been lifted in 2002, even though the CIA continued to file legal documents saying his status was covert. The judge found that the CIA intentionally misled the court and reinstated the case against Brown.
