US will become 'nation of chumps' if Congress allows FBI's warrantless surveillance of Americans, Turley warns

Congress must overhaul a federal law that has allowed the FBI to surveil American citizens without a warrant, according to experts who testified to lawmakers.

Section 702 of FISA allows surveillance of non-U.S. citizens overseas, and when U.S. citizens are flagged in these investigations, the FBI takes over the process of querying them for possible security issues. Aaron Kliegman is a politics reporter for Fox News Digital. 

In other words, if an American communicates with a foreigner who's under surveillance, the American's communications will also be swept up incidentally — and therefore potentially accessible to government agents. While the government needs a warrant from a special FISA court to begin surveillance of a foreigner abroad, a warrant isn't required to examine those communications once they're collected, even if they involve a U.S. citizen.
