IN HER FIRST APPEARANCE representing the American public before the top-secret Foreign Intelligence Surveillance Court in 2015, Amy Jeffress argued that the FBI is violating the Fourth Amendment by giving agents “virtually unrestricted” access to data from one of the NSA’s largest surveillance programs, which includes an untold amount of communications involving innocent Americans.
The NSA harvests data from major Internet companies like Facebook, Google and Apple without a warrant, because it is ostensibly “targeting” only foreigners. But the surveillance program sweeps up a large number of Americans’ communications as well. Then vast amounts of data from the program, including the Americans’ communications, are entered into a master database that a Justice Department lawyer at the 2015 hearing described as the “FBI’s ‘Google’ of its lawfully acquired information.”
The FBI routinely searches this database during ordinary criminal investigations — which gives them access to Americans’ communications without a warrant.
