The Electronic Frontier Foundation sued the NSA and government agencies on behalf of AT&T customers. EFF argues that the government’s dragnet surveillance of AT&T customers’ communications is unconstitutional. The Reporters Committee for Freedom of the Press, and 18 other media organizations, filed an amicus brief in support of EFF’s motion for partial summary judgment. The media coalition argues that widespread surveillance has a corrosive effect on journalists’ ability to report on matters of public interest. Journalists rely on confidentiality when developing stories about sensitive topics, but reporters and editors at major news outlets have said that NSA surveillance programs have made sources less willing to talk with them.
