The Supreme Court considered Tuesday whether to get rid of limits on how much political parties can spend coordinating with candidates, hearing a case brought by Republican candidates including Vice President J.D. Vance and potentially paving the way for wealthy donors to spend thousands more directly supporting candidates’ campaigns—though justices didn’t give a strong hint on how they could rule.

The Supreme Court heard oral arguments in National Republican Senatorial Committee (NRSC) v. Federal Election Commission (FEC), a case brought by Republican campaign committees, Vice President J.D. Vance—from his time as a senator—and former Rep. Steven Joseph Chabot, R-Ohio.

The case challenges a longstanding rule that limits how much political parties can spend coordinating directly with candidates, meaning payments for goods and services that directly benefit a candidate’s campaign.
