Twitter sued the U.S. government on Tuesday, seeking the ability to release a full report on government surveillance requests.

The company, in a lawsuit against the Justice Department and the FBI filed in federal court in northern California, claimed the government has been violating its free-speech rights by restricting it from releasing the full version of a report prepared earlier this year.

"Twitter's ability to respond to government statements about national security surveillance activities and to discuss the actual surveillance of Twitter users is being unconstitutionally restricted by statutes that prohibit and even criminalize a service provider's isclosure of the number of national security letters ("NSLs") and court orders issued pursuant to FISA that it has received, if any," the 19-page lawsuit claimed.
