Congressional reports originate from congressional committees and deal with proposed legislation or issues under investigation. Congress issues different types of reports, including committee reports, conference reports and executive reports.Congressional reports may be issued by the House or Senate. Depending on the chamber of origin, report citations begin with the Congress number during which it was issued and either H. Rpt. or S. Rpt., and an accession number (e.g., 112 H. Rpt. 1). Congressional reports are compiled in the U.S. Congressional Serial Set.
