National security letters (NSL) are secret orders that the FBI uses on a regular basis to obtain sensitive electronic data and phone records.
Companies that receive NSLs might not be legally required to hand over the information demanded by the FBI. The Intercept continues:
"The FBI’s internal guidelines suggest that the bureau uses the letters to demand sensitive information on email transactions — even though the Justice Department has specifically advised the FBI that it does not have the authority to use the letters this way. The documents also indicate that the FBI can use national security letters to surveil a “community of interest” by obtaining information from a business about a customer and every person that customer has contacted. This is a controversial practice that the bureau once halted amid scrutiny. But the documents reveal that a secretive unit that mines phone records can still initiate such requests."
