On May 19, the Federal Election Commission filed a brief in National Republican Senatorial Committee v Federal Election Commission, 24-3051. This is the case that challenges the federal law that limits how much money a party can spend on campaigns for its nominees if the party and the candidate coordinate with each other.
The FEC brief says the federal law is unconstitutional. Normally government attorneys defend the constitutionality of challenged laws, but in this case, both sides agree that the law should be struck down. The FEC recommends that the U.S. Supreme Court appoint an amicus curiae to defend the law.
