Prohibits a wire or electronic communications service provider from disclosing that the Federal Bureau of Investigation (FBI) has sought or obtained access to information or records if the Director of the FBI certifies that such disclosure may result in a danger to national security, interference with a criminal counterterrorism or counterintelligence investigation, interference with diplomatic relations, or a danger to the life or physical safety of any person.
