Illinois Senate President John Cullerton's 26-year-old son was stopped while driving a vehicle registered to the state and cited for Driving Under the Influence.
Garritt M. Cullerton had a blood alcohol level of .188 when he was stopped just after midnight Sunday morning in downtown Chicago, police told the Chicago Tribune. That's twice the legal limit of .08.
Garritt Cullerton was charged with DUI, negligent driving and improper lane usage, police told NBC Chicago.
"A Senate vehicle assigned to the Senate President for official legislative business was used by his son without his authorization," Sen. Cullerton's office said in a written statement. "The Senate President is dissapointed that this incident occurred and takes this matter very seriously. He will work to ensure that this does not occur in the future."
