Answer:
Interest groups and lobbying activities can be regulated through:
1. Registration of interest groups and lobbyists with the Federal Government.
2. Prohibiting contacts between lobbyists and Congress members (according to The Honest Leadership and Open Government Act of 2007)
3. Prohibition of gifts and compensations for successful lobbying.
4. Disclosure and scrutiny of money spent in lobbying.
Some of the goals of these regulations enable restrictions to lobbying among lawmakers, promote transparency, limit the influence lobbying has on legislation and to penalize corrupt systems.
