Military Expands Intelligence Role in U.S. - New York Times:
The Pentagon has been using a little-known power to obtain banking and credit records of hundreds of Americans and others suspected of terrorism or espionage inside the United States, part of an aggressive expansion by the military into domestic intelligence gathering.
The C.I.A. has also been issuing what are known as national security letters to gain access to financial records from American companies, though it has done so only rarely, intelligence officials say.
Banks, credit card companies and other financial institutions receiving the letters usually have turned over documents voluntarily, allowing investigators to examine the financial assets and transactions of American military personnel and civilians, officials say.
The F.B.I., the lead agency on domestic counterterrorism and espionage, has issued thousands of national security letters since the attacks of Sept. 11, 2001, provoking criticism and court challenges from civil liberties advocates who see them as unjustified intrusions into Americans’ private lives.
But it was not previously known, even to some senior counterterrorism officials, that the Pentagon and the Central Intelligence Agency have been using their own “noncompulsory” versions of the letters. Congress has rejected several attempts by the two agencies since 2001 for authority to issue mandatory letters, in part because of concerns about the dangers of expanding their role in domestic spying.
