The Foreign Intelligence Surveillance Authority Act, also called FISA, is set to expire on April 19, meaning time is running short for Congress to reauthorize the law. The sticking point lies in Section 702, which allows U.S. authorities to surveil communications of foreigners without a warrant.

Because those foreigners often contact Americans, their info is also swept up in data collection. As a result, the FBI can conduct searches on American data collected through the law without a warrant. Many conservatives have balked at the function and are now relentlessly pushing House Speaker Mike Johnson, R-La., to reform FISA with a new warrant requirement for authorities to sift through data.
