SAN FRANCISCO — Federal officials on Tuesday released previously classified documents showing misuse of a domestic spying program in 2009.
The Obama administration has been facing mounting pressure to reveal more details about the government’s domestic surveillance program since a former intelligence contractor released documents showing massive National Security Agency trawling of domestic data.
The information included domestic telephone numbers, calling patterns and the agency’s collection of Americans’ Internet user names, IP addresses and other metadata swept up in surveillance of foreign terror suspects.
The documents released Tuesday relate to a time in 2009 when U.S. spies went too far in collecting domestic phone data and then mislead a secret spy court about their activities.
The documents came in response to a lawsuit filed by the Electronic Frontier Foundation.
A federal judge in 2011 said in a declassified order that he was troubled by at least three incidents over three years where government officials admitted to mistaken collection of domestic data.
