Illinois Senate President John Cullerton was arrested and charged with assault after he allegedly threatened a bouncer in a Wicker Park or was it his idiot son

The son of Illinois Senate President John Cullerton was arrested and charged with assault after he allegedly threatened a bouncer in a Wicker Park bar, police said.

Garritt M. Cullerton, 28, was at the Innjoy bar in the 2000 block of West Division Street Sunday night when he told a bouncer, "I am going to punch you in the face. I'm going to (expletive) knock you out," according to a police report.

He was arrested and charged with misdemeanor assault, said Chicago Police News Affairs Officer Darryl Baety. Cullerton was released on a personal recognizance bond.

Cullerton, the son of state Sen. John Cullerton, has had other run-ins with the law.

He pleaded guilty in January 2011 to a misdemeanor DUI charge and was given 2 years of conditional discharge and ordered to pay a $1,250 fine, which he has not paid, according to court records.

In April of 2010, Cullerton was arrested and found to have a blood-alcohol level of 0.188 when he was pulled over in a state issued SUV provided to his father. Cullerton was arrested in the 800 block of North Dearborn Street shortly after midnight, police said.

Cullerton was cited with driving under the influence, negligent driving and improper lane usage, police said. He was driving a 2009 Ford Escape registered to the state Senate, according to records and police.

Cullerton has not paid his fine and has a July 17 court date on that matter, according to court records.

A Senate spokeswoman for Sen. Cullerton said his office would have no comment on the arrest because it is not related to the office or state business.
