The Registry of Motor Vehicles has issued President Obama’s uncle, Onyango Obama, a hardship driver’s license so he can continue to work as a manager at two Metrowest liquor stores, six days after he resolved a drunk driving case in court. On March 27, Obama appeared in Framingham District Court and admitted that his blood alcohol level was .14 when he was arrested by a Framingham police Office Val Krishtal last Aug. 24. A judge continued the case without a finding for one year, meaning it will be dismissed if Obama’s record stays clean.
