AUGUSTA, Maine (AP) — Maine is set to slash fines lodged against backers of a failed casino effort from half a million dollars to $100,000.

The Maine ethics commission voted 4-0 Wednesday to accept the settlement. Commission staff said it's unlikely Maine will be able to recover the full record-high penalty for campaign finance law violations.

The commission released records showing how casino developer Shawn Scott and other partners funded a $4 million push to gather signatures and get the casino proposal in front of voters last year.

The fine will be paid by Scott's sister Lisa Scott and the campaign's treasurer Cheryl Timberlake. The two haven't responded to requests for comment.
