While Americans are typically protected from unwarranted searches by the Fourth Amendment, some of their data gets caught when NSA collects intelligence on foreigners living overseas. This year's report also reveals that the NSA monitored the communication of an estimated 164,770 foreign individuals or groups in 2018, compared to 129,080 in 2017. As TechCrunch reports, that marks the largest year-over-year increase in foreign surveillance. In 2013, the NSA monitored the communication of just 89,138 foreigners.
Perhaps one silver lining is that the NSA collected fewer American phone records in 2018 -- 434.2 million, down from 534.3 million in 2017. But that's still a significant jump from 2016, when it collected 151.2 million records. These numbers might look a bit different next year, as the NSA has formally recommended the White House drop the phone surveillance program that collected that call information.
