The ACLU announces: "The ACLU has filed a lawsuit challenging the constitutionality of the NSA’s mass interception and searching of Americans’ international communications. At issue is the NSA's “upstream” surveillance, through which the U.S. government monitors almost all international – and many domestic – text-based communications. The ACLU’s lawsuit, filed in March 2015 in the U.S. District Court for the District of Maryland, is brought on behalf of nearly a dozen educational, legal, human rights, and media organizations that collectively engage in hundreds of billions of sensitive Internet communications and have been harmed by NSA surveillance." The named plaintiff, Wikimedia, notes: "Our lawsuit says that the N.S.A.’s mass surveillance of Internet traffic on American soil — often called “upstream” surveillance — violates the Fourth Amendment, which protects the right to privacy, as well as the First Amendment, which protects the freedoms of expression and association."
