The CIA has paid $150,000 to settle a lawsuit brought by a former employe who claimed his firing five years ago violated his First Amendment rights.

The employe, Donald S. Jordan, a 29-year veteran of the agency who worked in the CIA's domestic collection division and headed its San Diego office, sued the agency and former director Stansfield Turner for $250,000. Jordan claimed that he was fired for sending Turner a telegram protesting the use of CIA files kept on employes who criticize the agency. The agency maintained he was fired for insubordination.

In a court document made public yesterday in U. S. District Court here, Judge Louis Oberdorfer said the suit had been dismissed and that a check for $150,000 had been delivered to Jordan.

Jordan's attorney, Richard B. Sobol, said the settlement ends years of judicial maneuvering by the government to dismiss the case and that the precise terms of the settlement are under seal.

Since his dismissal, Jordan has criticized the domestic collection division, which interviews U.S. citizens upon their return from travels abroad and in particular to eastern bloc countries, maintaining that it is inefficient, overstaffed and collects useless information that is sometimes fabricated.
