It is not first time Cullerton has been in trouble with the law. He pleaded guilty in January 2011 to a misdemeanor DUI charge. He was arrested driving an SUV registered to the state Senate when he was stopped in the 800 block of North Dearborn in the early morning hours of April 18, 2010.

Police said he registered a blood-alcohol level of 0.188, more than twice the legal limit. He was also ticketed for improper lane usage. Cullerton was sentenced to two years probation, fined $1,250, ordered to perform 240 hours of community service and ordered to seek treatment for alcohol abuse.

He was also charged with DUI in 2004 and 2008, but not convicted.
