The Supreme Court ruled 6-3 in favor of Senator Ted Cruz (R., Texas) on Monday, striking down a rule that prevented him from repaying debt from his 2018 Senatorial campaign.

The case, FEC v. Cruz, was brought by Cruz after he attempted to repay his campaign’s considerable debt with political contributions raised in his name. Cruz, whose wife Heidi was a banker with Goldman Sachs, had lent $260,000 of his personal money to his campaign. Section 304 of the Bipartisan Campaign Reform Act of 2002 limited the use of contributions in excess of $250,000 to repay debt 20 days after an election, which left Cruz $10,000 due.

The U.S. District Court for the District of Columbia summarily ruled in favor of Cruz’s constitutional claim, that the cap was a limit on the First Amendment and “burdened political speech without sufficient justification.”
