Campaign Legal Center (CLC) is a nonprofit 501(c)(3) government watchdog group in the United States.

[4] CLC was critical of former vice-presidential candidate John Edwards's use of charity organizations which he had founded, complaining they were being used chiefly to keep himself in the public eye in preparation for a possible 2008 presidential run.

[5] The group filed an amicus brief in the 2007 landmark Supreme Court case Citizens United v. Federal Election Commission, unsuccessfully urging the Court not to strike down a provision of McCain-Feingold which prevented unlimited political contributions to organizations not directly affiliated with Federal candidates.

[23] That same year, CLC filed several complaints with the FEC alleging illegal coordination between the Trump campaign and the National Rifle Association.

[24][25] CLC’s Potter also appeared on Face the Nation[26] and 60 Minutes[27] in 2018 to discuss President Trump’s potential campaign finance violations related to the hush money paid by Michael Cohen to Stormy Daniels.

[36][37][38] In 2021, CLC sued the FEC for refusing to launch an investigation into Donald Trump's presidential campaign over allegations that it coordinated with a super PAC.

[41][42] It was intended to expand voting rights, change campaign finance laws to reduce the influence of money in politics, ban partisan gerrymandering, and create new ethics rules for federal officeholders.
