Rule 5.3.  Clearing the Chamber

In case of disturbance or disorderly conduct, the presiding officer, or chairman of the Committee of the Whole, may, or at the request of one-third of those present and voting, shall clear the entire Chamber, or any part thereof, including the gallery, Memorial Hall, or other environs, of any or all persons causing or creating the disturbance.  This rule shall not apply to any member of the news media, unless it has been determined that such member is causing or creating the disturbance or is guilty of disorderly conduct.  Any person, persons, or groups of persons may be readmitted to the House Chamber upon approval of the Speaker or a majority of the House members present and voting.
