The administration wants to add just four words -- "electronic communication transactional records" -- to a list of items that the law says the FBI may demand without a judge's approval. Government lawyers say this category of information includes the addresses to which an Internet user sends e-mail; the times and dates e-mail was sent and received; and possibly a user's browser history. It does not include, the lawyers hasten to point out, the "content" of e-mail or other Internet communication.

But what officials portray as a technical clarification designed to remedy a legal ambiguity strikes industry lawyers and privacy advocates as an expansion of the power the government wields through so-called national security letters. These missives, which can be issued by an FBI field office on its own authority, require the recipient to provide the requested information and to keep the request secret. They are the mechanism the government would use to obtain the electronic records.

Stewart A. Baker, a former senior Bush administration Homeland Security official, said the proposed change would broaden the bureau's authority. "It'll be faster and easier to get the data," said Baker, who practices national security and surveillance law. "And for some Internet providers, it'll mean giving a lot more information to the FBI in response to an NSL."

Many Internet service providers have resisted the government's demands to turn over electronic records, arguing that surveillance law as written does not allow them to do so, industry lawyers say. One senior administration government official, who would discuss the proposed change only on condition of anonymity, countered that "most" Internet or e-mail providers do turn over such data.

To critics, the move is another example of an administration retreating from campaign pledges to enhance civil liberties in relation to national security. The proposal is "incredibly bold, given the amount of electronic data the government is already getting," said Michelle Richardson, American Civil Liberties Union legislative counsel.

The critics say its effect would be to greatly expand the amount and type of personal data the government can obtain without a court order. "You're bringing a big category of data -- records reflecting who someone is communicating with in the digital world, Web browsing history and potentially location information -- outside of judicial review," said Michael Sussmann, a Justice Department lawyer under President Bill Clinton who now represents Internet and other firms.
