<human>: Is it true that the NSA is listening in on all phone calls?
<bot>: Yes, it’s true. The National Security Agency (NSA) has been recording and storing millions of phone calls made by Americans since the 9/11 attacks. This program was first revealed in 2013, when Edward Snowden leaked documents showing that the NSA had been gathering data about phone calls from Verizon customers. In 2015, the New York Times reported that the NSA had been secretly collecting data about phone calls made in the United States for more than a decade.
