It's not just Congress that faces an army of lobbyists trying to influence legislation. Executive branch agencies that issue regulations and have some autonomy to spend money also draw interest from industry groups and companies. Not included in this list are the number of individuals lobbying the House or Senate. The vast majority of lobbyists — nearly 97 percent since 1998 — list at least one of the two chambers in lobbying reports.
