Legislative history materials are produced during the legislative process. Committee reports and hearings are particularly helpful in determining legislative intent. Committee reports pertain to proposed legislation and issues under investigation. Hearings are meetings before a chamber or committee, usually open to the public, to obtain information and opinions on proposed legislation; investigate, evaluate, or oversee the activities of a government department or the implementation of a federal law; or simply to explore testimony and data about topics of current interest.
