The leadership of a legislative house consists of individuals who are chosen by their peers from the ranks of the elected representatives. The Assembly Chief Clerk, the Secretary of the Senate, and the Chief Sergeants-at-Arms are not elected officials, but are appointed to their offices by the members of the legislature.
The word "caucus" generally refers to a group of legislators who come together in a formal association to pursue a common interest in specific issues. Such caucuses usually consist of legislators from more than one political party. A caucus may also consist of all legislators who belong to one political party. The word can also refer to a closed meeting of legislators of one political party.
