Last year, NSA announced it started deleting records collected under the program prior to 2015 because of technical challenges with handling and storing the data. Since then, lawmakers said, officials have not issued any updates on the program.
“A public status report will resolve the current confusion, demonstrate the NSA’s commitment to transparency, and inform Congress’s deliberations about the possible reauthorization of the program later this year,” Sens. Ron Wyden, D-Ore., Mark Warner, D-Va., Martin Heinrich, D-N.M., Dianne Feinstein, D-Calif., Kamala Harris, D-Calif., and Michael Bennet, D.Colo., said in a letter to NSA Director Gen. Paul Nakasone.
