The National Security Agency destroyed surveillance data it pledged to preserve in connection with pending lawsuits and apparently never took some of the steps it told a federal court it had taken to make sure the information wasn’t destroyed, according to recent court filings.

Word of the NSA’s foul-up is emerging just as Congress has extended for six years the legal authority the agency uses for much of its surveillance work conducted through U.S. internet providers and tech firms. President Donald Trump signed that measure into law Friday.
