Although the caucus has had membership from both houses of Congress, it has had much less presence in the Senate, and some representatives choose to leave the caucus when they become senators (or when seeking such office). Other representatives have left the caucus when joining House leadership. Members who have attained higher office outside of Congress, having left that body, are no longer in the caucus.
