The FBI and NSA use Section 215 of the USA PATRIOT Act to collect vast amounts of information about people in the United States without a warrant. In 2018, under only one of two Section 215 provisions, the government collected 434,238,543 call records. The vast majority of those records relate to people who are not the targets of any investigations or suspected of wrongdoing. The government can use Section 215 for many other purposes, including the collection of location information, medical information, and purchase records. The government discloses few details about those uses. Section 215 is scheduled to sunset on December 15, 2019.
