Google, Facebook, Yahoo and industry and civil rights groups have opposed legislation that would extend the categories of Internet records that the U.S. government can collect without court approval through administrative orders known as National Security Letters. The groups are concerned with the expansion of the scope of NSLs because the government already uses them to a great extent, most often accompanied by gag orders prohibiting companies from making public that they have received such requests. Under current rules, the FBI can obtain phone records with a NSL, but not the email records.”]
