The Foreign Intelligence Surveillance Act's Section 702, which authorizes the NSA's warrantless data gathering, is supposed to expire on New Year's Eve. Don't tell that to the White House, though. Lawyers for the executive branch have determined that FISA Section 702 surveillance can legally continue until April 26th, 2018. The rationale comes down to a technicality. As the FISA Amendments Act says orders issued under 702 can continue for a year, and the last year-long certification was issued on April 26th, 2017... well, you do the math.
