On the other hand (from the same article):

The NSA doesn’t need court approval each time it searches Americans’ phone records.
NSA Deputy Director John Inglis said that 22 NSA officials are authorized to approve requests to query an agency database that contains the cellphone metadata of American citizens. (Metadata includes the numbers of incoming and outgoing calls, the date and time the calls took place, and their duration.) Deputy AG Cole also said that all queries of this database must be documented and can be subject to audits. Cole also said that the the NSA does not have to get separate Foreign Intelligence Surveillance Court (FISC) approval for each query; instead, the agency merely has to file a monthly report with the court on how many times the database was queried, and how many of those searches targeted the phone records of Americans.
