Classified documents published by news site The Intercept state that ICREACH is accessible to 23 government agencies, including the FBI, Drug Enforcement Administration, and the CIA, and was designed to store more than 850 billion records about phone calls, emails, cellphone locations, and text messages. 
According to Ryan Gallagher, the reporter for The Intercept who revealed the ICREACH program, the data accessed through the system is "swept up and stored on this database en masse using this Reagan-era presidential order, which is called Executive Order 12333. And this thing is subject to no court oversight from the secret foreign intelligence court and minimal congressional scrutiny."
