The instrument that compels testimony or the production of documents is a subpoena. It is a formal court or authorized-body order requiring a person to appear to testify (subpoena ad testificandum) or to produce specified records or evidence (subpoena duces tecum). Grand jury subpoenas are a specific use of this same instrument in grand jury investigations. National Security Letters are government demands for records issued under specific statutes and often with secrecy requirements, not the general tool for court-ordered testimony or production. Periodic Statements are regular banking statements and do not compel testimony or evidence.
