Gov. Eric Greitens was fined by the Missouri Ethics Commission Friday for violating a state campaign ethics law.According to The Associated Press, Greitens failed to report that his gubernatorial campaign obtained a donor list from the The Mission Continues, a nonprofit that he founded to help military veterans.Federal law prohibits charities such as The Mission Continues from intervening in political campaigns on behalf of candidates. The Internal Revenue Service has ruled charities cannot give donor lists to politicians but can rent them at fair market value if made available to all candidates.Greitens’ campaign filed amended campaign finance reports Friday placing the value of the list at $600.We concur with Greitens uber-adviser and wunderkind Austin Chambers that this wasn’t a major ethics violation. Greitens was fined $1,000 and will only have to pay $100 of that if he commits no other campaign finance violations during the next two years.It’s a little harder to swallow his characterization that this was just a clerical error where a minor contribution wasn’t reported on a campaign-finance report.According to the Associated Press, Greitens raised about $2 million from supporters of The Mission Continues. Presumably, a chunk of that came from the donor list although Greitens denied using it to raise contributions back in October.What is more troubling is that Greitens’ ethics violation is part of a pattern of nondisclosures that is rapidly becoming his albatross.The Republican governor declined to release his tax returns, refused to disclose contributors who poured over $2 million in so-called “dark money” into his campaign and won’t provide the amount of donations contributors provided for his inauguration celebration.Predictably, Democrats and a growing number of critics in his own party, are calling bull chips on the governor who ran hard on a platform of cleaning up the culture of corruption in Jefferson City.You can’t blame them. With an ethics violation under his belt, Greitens looks more and more like a business as usual politician rather than the guy who was going to drain the swamp.Greitens said he was going to usher in a new era of open, honest and ethical government. He can still make good on that pledge. It starts by pulling the curtain and letting the sun in on some of the things he’s kept secret. It’s always easier to be ethical in the light.
