Summary

Investigators can issue subpoenas to make people attend, testify, and produce evidence. They have the same power as a U.S. district court in civil matters in the district where the investigation happens. If someone refuses, the district court can order them to comply and punish contempt. Witnesses get travel and attendance pay at federal rates and can be sworn.
