The Foreign Intelligence Surveillance Court (FISA) renewed the NSA's authority to collect metadata from users calls again, earlier this week. The standard for the program requires a reassessment every 90 days, but typically authorities will fly under the radar.
The Director of National Intelligence publicized the action "in order to provide the public with a more thorough and balanced understanding of the program." The announcement reasserts the programs legality, citing the "holdings of the United States District Courts of the Southern District of New York and Southern District of California, as well as the findings of 15 judges of the Foreign Intelligence Surveillance Court on 36 separate occasions over the last seven years."
The program is designed in ways to "achieve our counterterrorism mission in a manner that gives the American people greater confidence."
