Applications to target a U.S. person under Title I must be accompanied by a certification from a
senior national security official, which may include the Director or Deputy Director of the FBI.
They must then be approved by the Attorney General, the Deputy Attorney General, or the Assistant Attorney General for National Security.
If one of those officials approves an application, it is then sent to the Foreign Intelligence Surveillance Court (FISC), which consists of judges selected by the Chief Justice of the U.S. Supreme Court who serve on a rotating basis.
The house of cards coming down.
