The correct answer is, besides legislators, other people can attend the sessions.
Legislative sessions are opened to the public. Any time the legislators are in session, the general public can attend. There are staff members in the sessions such as the secretaries that took the minutes. There is also the media. Reporters and cameramen can enter the legislative session to later inform the public of any important resolution. For instance, if an individual wants to attend a session in the Senate or the House, the person can get a pass through the office of his representative or senator.
