Legislative Debates & Proceedings are statements made and/or actions taken in a chamber of Congress. Floor debates may occur at any time on a bill and they are recorded in the daily publication, Congressional Record.
Legislative debates may include statements by a bill’s sponsors or the chairs of the committees considering the bills, which are given more weight than comments by Representatives or Senators not involved with the specific bill. However, statements may be contradictory (making it difficult to infer the intent) and can be altered prior to publication.
Bluebook Rule 13.5
"Cite congressional debates after 1873 to the Congressional Record; use the daily edition only for matter not yet appearing in the permanent edition. The primary ways in which the Congressional Record differs from the daily edition are continuous pagination, altered text, and the dropping of the prefixes H, S, and E before page numbers:"
