The FBI is trying to get the information of everyone who read a specific USA Today article at a specific time as part of an investigation. The FBI issued a subpoena demanding the IP addresses and mobile identification information that would pinpoint those who accessed a Feb. 2 article about a shooting that killed two agents and wounded three others as they tried to serve a warrant in Florida. The subpoena, which demanded the information of those who accessed the story during a 35-minute window starting at 8:03 p.m. on the day of the shooting, was issued in April but only became public recently as Gannett, USA Today’s parent company, fought it in court.
