FBI Director Chris Wray admitted that the agency rarely has probable cause when performing backdoor searches of NSA collections, sparking concerns about the constitutionality of the practice. The FBI is pushing for continued warrantless access to domestic communications, despite opposition from some lawmakers and privacy advocates. A proposed reform bill would require a warrant for such searches, but the FBI argues that this would be impractical and ineffective. The issue has sparked debate about the balance between national security and individual privacy.
