Another set of documents shows the judges of the FISA court seemed satisfied with the NSA's cooperation. It says that in September 2009, the NSA advised the Senate Intelligence Committee about its continuing collection of Americans' phone records and described a series of demonstrations and briefings it conducted for three judges on the secretive U.S. spy court.
The memorandum said the judges were “engaged throughout and asked questions, which were answered by the briefers and other subject matter experts,” and said the judges appreciated the amount and quality of information the NSA provided.
It said that two days later, one of the judges, U.S. District Judge Reggie Walton, renewed the court's permission to resume collecting phone records.
The documents also included previously classified testimony from 2009 for the House Intelligence Committee by Michael Leiter, then head of the National Counterterrorism Center.
He and other officials said collecting Americans' phone records helped indict Najibullah Zazi, who was accused in a previously disclosed 2009 terror plot to bomb the New York City subways.
