The American Civil Liberties Union has sued federal agencies for records related to their “social media surveillance activities.”

The ACLU lawsuit, filed Thursday in the U.S. District Court for the Northern District of California, claims that the “failure” of seven government agencies to respond to a request for information pertaining to the “surveillance of social media users and speech” violates the Freedom of Information Act and raises concerns for freedom of speech and privacy of both “citizens and noncitizens alike.”
