The National Republican Senatorial Committee (NRSC) filed suit to challenge longstanding limits on how much political parties can spend in “coordination” with federal candidates. Campaign Legal Center has joined the case as an amicus curiae to help defend the coordinated spending limits, arguing the lawsuit is foreclosed by a that a 2001 decision by the Supreme Court upheld these federal limits because they prevented donors from routing big money to candidates through party committees. 

In 2023, Minnesota enacted a law prohibiting corporations with foreign owners from spending to influence Minnesota state elections. The Minnesota Chamber of Commerce sued to overturn the law on First Amendment and federal preemption grounds, and CLC has joined the case as an amicus curiae to help defend the law.

Campaign Legal Center is participating in the defense of Maine Question 2, known as the “Prohibit Foreign Spending in Elections Initiative,” in four lawsuits challenging the constitutionality of the initiative. CLC represents Protect Maine Elections, the ballot measure committee that was founded to help draft and enact Question 2.
