The biggest supermarket merger in U.S. history is now in the hands of a federal judge. Government regulators are asking a district court in Oregon to stop the deal between Kroger and Albertsons, the top two U.S. supermarkets. Kroger owns Fred Meyer, King Soopers, Harris Teeter and Ralphs while Albertsons owns Vons and Safeway. The $25 billion merger has been under review for almost two years.
