US launches drive to plug leaks:

The Bush administration has launched several investigations to discourage government employees from leaking classified information to news reporters, The Washington Post reported in its Sunday edition. FBI agents have interviewed dozens of employees at the CIA, the National Security Agency and other intelligence agencies in recent weeks as they investigate possible leaks that led to reports about the NSA’s domestic spying program and secret CIA prisons in Eastern Europe, the Post said. Employees at the FBI, the CIA, the Justice Department and other agencies have also received Justice Department letters prohibiting them from discussing the NSA program, the Post said, citing anonymous sources.
