Thomas Dowling, a San Francisco lobbyist who appeared before Congress as a pro-Contra Catholic priest, received funds from a public relations firm linked to Lt. Col. Oliver North. Dowling is not a Roman Catholic priest, although congressional and State Department officials leaders say they believed he was. This story reports that Congressman Sam Gejdenson, member of a House subcommittee before which Dowling appeared, will now demand that all witnesses be sworn in before they testify.
