Aug. 13, 2007 issue – The controversy over President Bush’s warrantless surveillance program took another surprise turn last week when a team of FBI agents, armed with a classified search warrant, raided the suburban Washington home of a former Justice Department lawyer. The lawyer, Thomas M. Tamm, previously worked in Justice’s Office of Intelligence Policy and Review (OIPR)—the supersecret unit that oversees surveillance of terrorist and espionage targets. The agents seized Tamm’s desktop computer, two of his children’s laptops and a cache of personal files. Tamm and his lawyer, Paul Kemp, declined any comment. So did the FBI. But two legal sources who asked not to be identified talking about an ongoing case told NEWSWEEK the raid was related to a Justice criminal probe into who leaked details of the warrantless eavesdropping program to the news media. The raid appears to be the first significant development in the probe since The New York Times reported in December 2005 that Bush had authorized the National Security Agency to eavesdrop on the international phone calls and e-mails of U.S. residents without court warrants.
