Dakota County authorities will investigate whether Republican Senator Rod Grams' son got special treatment from law enforcement during a July traffic stop. Grams had asked the Anoka County Sheriff to track down his 21-year-old son Morgan, who had failed to return a borrowed rental car. When deputies found Morgan Grams, they also discovered ten small bags of marijuana in the car. A juvenile was charged and later pleaded guilty to possession of a controlled substance. Grams was not charged and was escorted home. One of Senator Grams' DFL opponents says the case raises questions about equal justice under the law, but the chairman of the Minnesota Republican Party calls the story a political attack.
