The Obama administration is seeking to make it easier for the FBI to compel companies to turn over records of an individual’s Internet activity without a court order if agents deem the information relevant to a terrorism or intelligence investigation.

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.
