Committee staff writers research current issues before drafting new legislation or reviewing existing laws. They may also seek input from other members or staff members of the House or Senate concerning issues before them. Most frequently, they are attorneys who specialize in legislative work. However, anyone with policymaking authority may draft a brief arguing for or against legislation. Additionally, staff writers may be divided into subgroups based on specific expertise needed by the committee. For example, one writer might focus on military affairs while another focuses on economic issues related to their jurisdiction.
