The story of Tamm's phone call is an untold chapter in the history of the secret wars inside the Bush administration. The New York Times won a Pulitzer Prize for its story. The two reporters who worked on it each published books. Congress, after extensive debate, last summer passed a major new law to govern the way such surveillance is conducted. But Tamm—who was not the Times's only source, but played the key role in tipping off the paper—has not fared so well. The FBI has pursued him relentlessly for the past two and a half years. Agents have raided his house, hauled away personal possessions and grilled his wife, a teenage daughter and a grown son. More recently, they've been questioning Tamm's friends and associates about nearly every aspect of his life. Tamm has resisted pressure to plead to a felony for divulging classified information. But he is living under a pall, never sure if or when federal agents might arrest him.
