The ACLU has filed a lawsuit challenging the constitutionality of the NSA’s mass interception and searching of Americans’ international communications. Through a program called “Upstream,” the U.S. government monitors almost all text-based communications entering or leaving the United States, and many domestic communications as well. 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 who collectively engage in hundreds of billions of sensitive internet communications and have been harmed by NSA surveillance.
