Fla. Const. art. III, § 5

Each house, when in session, may compel attendance of witnesses and production of documents and other evidence upon any matter under investigation before it or any of its committees, and may punish by fine not exceeding one thousand dollars or imprisonment not exceeding ninety days, or both, any person not a member who has been guilty of disorderly or contemptuous conduct in its presence or has refused to obey its lawful summons or to answer lawful questions. Such powers, except the power to punish, may be conferred by law upon committees when the legislature is not in session. Punishment of contempt of an interim legislative committee shall be by judicial proceedings as prescribed by law.
