FISA Section 702

The FISA Amendments Act of 2008 is a law that amended the Foreign Intelligence Surveillance Act, allowing for warrantless surveillance of non-US persons abroad. The law was used as the basis for surveillance programs disclosed by Edward Snowden in 2013, including PRISM. The law allows the Attorney General and Director of National Intelligence to jointly authorize targeting of non-US persons, and permits the collection of communications of US persons incidentally, such as when they communicate with non-US persons who are the targets of the collection. The law has been extended several times, most recently in 2018 for six more years.learn more on wikipedia
