Super PACs were made possible in part by the Supreme Court's decision in Citizens United v. Federal Election Commission. The decision declared that limiting independent expenditures by corporations and unions violated their First Amendment rights, allowing them to spend unlimited amounts on political campaigns. This led to the formation of Super PACs, which are independent political action committees that can raise and spend unlimited amounts of money on political campaigns as long as they do not directly coordinate with the candidate's campaign.
