which type of committee is created to report to the house on specific issues?
Ad hoc and select committees are established to study specific issues, problems or questions. Sometimes these temporary committees are formed within a single chamber, or they are formed as joint committees with members from both chambers. Of these temporary committees, conference committees tend to be the most important in affecting legislation.
A committee created in the rules of either house that meets throughout the two years of a congressional session (e.g., the 109th Congress) to consider and report on measures referred or tasks assigned to it by the respective presiding officers.
