Independent PACs may solicit contributions from the general public and must pay their own costs from those funds. Federal multi-candidate PACs may contribute to candidates as follows: In its 2010 case "Citizens United v. FEC", the Supreme Court of the United States overturned sections of the Campaign Reform Act of 2002 (also known as the McCain-Feingold Act) that had prohibited corporate and union political independent expenditures in political campaigns. "Citizens United" made it legal for corporations and unions to spend from their general treasuries to finance independent expenditures related to campaigns, but did not alter the prohibition on direct corporate or union contributions to federal campaigns. Organizations seeking to contribute directly to federal candidate campaigns must still rely on traditional PACs for that purpose.', 'Independent PACs may solicit contributions from the general public and must pay their own costs from those funds']}}]}]
