18 U.S.C. § 3692

In all cases of contempt arising under the laws of the United States governing the issuance of injunctions or restraining orders in any case involving or growing out of a labor dispute, the accused shall enjoy the right to a speedy and public trial by an impartial jury of the State and district wherein the contempt shall have been committed. This section shall not apply to contempts committed in the presence of the court or so near thereto as to interfere directly with the administration of justice nor to the misbehavior, misconduct, or disobedience of any officer of the court in respect to the writs, orders or process of the court.
