"The C.I.A. just went and searched the committee's computers," Senator Dianne Feinstein said on Tuesday, in a speech on the Senate floor. She accused the Agency of sabotaging the oversight efforts of the Senate Select Committee on Intelligence, which she chairs, and thus the separation of powers; engaging in "a potential effort to intimidate this staff," by accusing them of "hacking"; breaking its word; and maybe breaking the law. "Besides the constitutional implications, the C.I.A. search may also have violated the Fourth Amendment, the Computer Fraud and Abuse Act, as well as Executive Order 12333, which prohibits the C.I.A. from conducting domestic searches or surveillance," she said. The C.I.A. spied on the Senate, and the senator is angry.
