The minority leader has a number of formal and informal party responsibilities. Formally, the rules of each party specify certain roles and responsibilities for their leader. For example, under Democratic rules for the 106th Congress, the minority leader may call meetings of the Democratic Caucus. He or she is a member of the Democratic Congressional Campaign Committee; names the members of the Democratic Leadership Council; chairs the Policy Committee; and heads the Steering Committee. Examples of other assignments are making "recommendations to the Speaker on all Democratic Members who shall serve as conferees" and nominating party members to the Committees on Rules and House Administration. Republican rules identify generally comparable functions for their top party leader.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): According to democratic rules of the 106th congress what leadership members do they appoint?
Democratic Leadership Council
