In aid of any investigation or proceeding, the Commission may order and otherwise provide for the inspection of papers, books, records, accounts, documents, transcriptions, and other physical things, and may issue subpoenas for attendance of witnesses and for the production of papers, books, records, accounts, transcriptions, documents, or other physical things, and testimony.
Whenever a person fails to appear to testify or to produce any papers, books, records, accounts, documents, transcriptions, or other physical things, as required by a subpoena issued by the Commission, the Commission may petition the United States District Court for the district in which the person may be found for an order compelling him or her to attend, testify, or produce the writings or things required by subpoena, pursuant to D.C. Official Code §§ 11-1527(c)(3).
