Lobbyists spend much of their time communicating with the people who affect legislation—principally the legislators and officials of federal and state governments. This communication takes place in person, by telephone, by e-mail, and by memoranda. Most of a lobbyist's time is spent gathering information, writing reports, creating publicity, and staying in touch with clients. They respond to the public and the news media when required. Sometimes their expertise is required at hearings, or they may testify before a legislature.
