§ 5713. Disobedience to subpoena
In case of disobedience to any such subpoena, the aid of any district court of the United States may be invoked in requiring the attendance and testimony of witnesses and the production of documentary evidence, and such court within the jurisdiction of which the inquiry is carried on may, in case of contumacy or refusal to obey a subpoena issued to any officer, agent, or employee of any corporation or to any other person, issue an order requiring such corporation or other person to appear or to give evidence touching the matter in question; and any failure to obey such order of the court may be punished by such court as a contempt thereof.
