Washington state attorneys asked a judge to fine the Grocery Manufacturers Association $43.8 million for campaign finance violations, a penalty that the association’s lawyer said was intended to ruin the trade group. The penalty would be by far the largest ever levied in Washington for not reporting campaign activities. In the biggest penalty to date, the Washington Education Association settled a case in 2008 by paying $975,000. Assistant Attorney General Garth Ahearn said GMA’s actions were unprecedented. The trade group schemed to conceal from voters the food and beverage companies that spent $11 million to defeat an initiative in 2013 that would have required labels on products with genetically engineered ingredients, he said. GMA reported itself as the source of the campaign contributions, but Hirsch ruled in March that GMA broke the law by not disclosing the companies the contributed to GMA. A trial to determine GMA’s penalty concluded Tuesday with closing arguments. Hirsch said she hoped to rule within a month.
