New York ? The Bush administration has asked federal judges in New York and Michigan to dismiss a pair of lawsuits filed over the National Security Agency’s domestic eavesdropping program, saying litigating them would jeopardize state secrets.

In papers filed late Friday, Justice Department lawyers said it would be impossible to defend the legality of the spying program without disclosing classified information that could be of value to suspected terrorists.

National Intelligence Director John Negroponte invoked the state secrets privilege on behalf of the administration, writing that disclosure of such information would cause “exceptionally grave damage” to national security.
