The attendance of any witness and production of evidence relevant to the inquiry may be required from any place in the United States.
In case of disobedience to a subpoena by any person, the Secretary may request the Attorney General to invoke the aid of any court of the United States within the jurisdiction in which the investigation is conducted, or where the person resides, is found, transacts business, is licensed to do business, or is incorporated, to require the attendance and testimony of any witness, the production of evidence, or the inspection of premises.
The Secretary shall publish procedures for the issuance of subpoenas under this section.
The procedures shall include a requirement that subpoenas be reviewed for legal sufficiency and, to be effective, be signed by the Secretary.
The United States district courts, the District Court of Guam, the District Court of the Northern Mariana Islands, the District Court of the Virgin Islands, the highest court of American Samoa, and the United States courts of the other territories and possessions are vested with jurisdiction in all cases arising under this chapter.
Any action arising under this chapter may be brought, and process may be served, in the judicial district where a violation or interference occurred or is about to occur, or where the person charged with the violation, interference, impending violation, impending interference, or failure to pay resides, is found, transacts business, is licensed to do business, or is incorporated.
