The Federal Election Commission is fining a super PAC for violating campaign-finance rules—nearly four years after the complaint was filed.

Restore Our Future, the super PAC that supported GOP presidential nominee Mitt Romney in 2012, has agreed to pay a civil penalty of $50,000 for airing an ad in the last election that was nearly identical to one that had originally been created and aired by the Romney campaign ahead of the 2007 primaries.
