when does a record of how members of congress voted on an issue have to be recorded in the journal
Congressional Record The Constitution, in Article I, Section 5, requires Congress to keep a journal of its proceedings, although the House and Senate Journals are separate publications from the Congressional Record, and include only a record of actions and votes, rather than verbatim texts of the debates.
Contempt of Congress Congressional rules empower all its standing committees with the authority to compel witnesses to produce testimony and documents for subjects under its jurisdiction. Committee rules may provide for the full committee to issue a subpoena, or permit subcommittees or the chairman (acting alone or with the ranking member) to issue subpoenas.
