The statement "Congress supervises how interest groups spend their money" is incorrect. Interest groups have significant autonomy in how they spend their money, including political donations.
While there are regulations and reporting requirements set by the Federal Election Commission (FEC), Congress does not directly supervise their spending.
Interest groups donate money to political campaigns to support candidates who are sympathetic to their views in hopes of gaining access to them once they are in office.
By supporting candidates, interest groups seek to influence legislation and policy decisions that align with their interests. Lawmakers often rely on interest groups and lobbyists to provide them with information about policy proposals and fellow lawmakers' stands, making access to sympathetic legislators crucial for interest groups.
Additionally, interest groups engage in electioneering to help elect candidates who favor their positions or to defeat those who oppose them. Political action committees (PACs) serve as special political arms for interest groups and make direct contributions to individual campaigns of selected candidates.
The relationship between interest groups and political parties is complex, with both entities working to advance their respective agendas and influence the political process
