US intelligence agencies are collecting billions of electronic records daily, according to a leaked government report.
The report, seen by Reuters, details how US intelligence, law enforcement and other agencies monitor the online activity of Americans and how they share that information with each other.
It is a far cry from the more than half-billion records the US government collects each year on Americans.
The NSA said in the report that it had no comment on the leak.
The agency has also been accused of collecting Americans’ private data, including phone records, on the suspicion that it can use that information to help track down terrorists.
The Obama administration has said that its surveillance of American phone records was legal under a law passed after the September 11, 2001, attacks.
But the report said the collection of metadata on phone calls was illegal, and that there was a strong likelihood that it was illegal.
The leak comes a day after the Senate Intelligence Committee voted down a bill to ban bulk collection of phone records by the NSA.
The bill, backed by the Senate Judiciary Committee, would have stopped bulk collection for now, but would have allowed the agency to keep a record of all phone calls for a year, as well as the content of those calls.
The USA Freedom Act would have also required that all phone records of Americans, even if stored overseas, be destroyed within a year.
A number of Democrats on the committee said that the USA Freedom act was unlikely to pass, and they were expected to vote against the bill on Tuesday.
The House of Representatives is expected to take up the bill after the recess on Wednesday.
