The U.S. National Security Agency collected more than 151 million records of Americans’ phone calls last year, even after Congress limited its ability to collect bulk phone records, according to an annual report issued on Tuesday by the top U.S. intelligence officer.

The report from the office of Director of National Intelligence Dan Coats was the first measure of the effects of the 2015 USA Freedom Act, which limited the NSA to collecting phone records and contacts of people U.S. and allied intelligence agencies suspect may have ties to terrorism.

It found that the NSA collected the 151 million records even though it had warrants from the secret Foreign Intelligence Surveillance court to spy on only 42 terrorism suspects in 2016, in addition to a handful identified the previous year.

The NSA has been gathering a vast quantity of telephone “metadata,” records of callers’ and recipients’ phone numbers and the times and durations of the calls – but not their content – since the September 11, 2001, attacks.
