Robert Litt, the general counsel at the Office of the Director of National Intelligence, told the Times that it was finalizing a 21-page draft of procedures to allow the expanded sharing. Separately, the Guardian reported earlier this month that the FBI had quietly changed its internal privacy rules to allow direct access to the NSA’s massive storehouse of communication data picked up on Internet service providers and websites.The revelations unnerved civil liberties advocates, who encouraged lawmakers to demand answers of the spy agency.“Under a policy like this, information collected by the NSA would be available to a host of federal agencies that may use it to investigate and prosecute domestic crimes,” said Neema Singh Guliani, legislative counsel and the American Civil Liberties Union. “Making such a change without authorization from Congress or the opportunity for debate would ignore public demands for greater transparency and oversight over intelligence activities.”In their letter this week, Lieu and Farenthold warned that the NSA’s changes would undermine Congress and unconstitutionally violate people’s privacy rights.
