Among the infractions he’s racked up is a speeding ticket for going 115 mph in a 65 mph zone and two previous DUIs.
Some of his previous arrests came as he was driving his father’s state issued vehicle, the Tribune reports, citing court records.
Cullerton was not convicted in the previous DUI cases, which came in 2004 and 2008. Instead he pleaded to lesser traffic offenses.
John Cullerton told the Tribune that he never intervened in his son’s legal affairs and expressed concern for his son’s wild ways.
"My wife and I and family are very concerned about our son," John Cullerton told the paper. "We want to make sure that we help him in any way we can. So it's a close family, and we're going to try to do anything we can to help him."
The senate president said that following his son’s recent “unauthorized” use of his vehicle he would move it from his home to his downtown office.
