Patrick J. O'Connor

In May 2013, O'Connor suggested that the Catholic Church and other religious institutions and not for profit organizations should pay property taxes and be billed for water provided by the City of Chicago. O'Connor's comments were in support of a plan by Mayor Rahm Emanuel to charge such organizations for water which had traditionally been provided without charge to not for profit organizations. “The silliest things can be said and people latch onto it.” O’Connor said. “For Chrissake, we sell everybody water! And now all of a sudden because we’re a church, we’re not supposed to sell them water? At some point, i think what’s gonna happen is someone’s gonna say how about looking at property taxes? We’ll give ya free water. How about paying for the property you own.” O'Connor further suggested that the Catholic Church should not criticize the plan to bill it for water use, but ought to address its clerical abuse scandals.

On Tuesday, March 3, 2009 O'Connor finished fifth in a 12-way race in the primary election for the Democratic Party nomination for the United States House of Representatives in the special election called to replace US Rep. Rahm Emanuel in Illinois's 5th congressional district.

In 2008 O'Connor was found to be one of seven Chicago aldermen who between them got ten of their children good-paying summer jobs with the Metropolitan Water Reclamation District of Greater Chicago.

O'Connor and the ward organization he chairs, the 40th Ward Regular Democratic Organization, were cited in a complaint filed on August 31, 2005 with the Illinois State Board of Elections by the Cook County Republican Party. The complaints charged that sixteen Democratic Party ward organizations are illegally housed in City-funded neighborhood ward offices. Taxpayers fund aldermanic service centers, which are open to the public. State law prohibits the use of public funds by any candidate for political or campaign purposes. The complaint against O'Connor and his ward organization was one of nine that a Hearing Officer appointed by the Board recommended proceed to the next step of the hearing process, an Open Preliminary Hearing. On October 17, 2005, at a regularly scheduled meeting, the Board entered an executive session and voted, in a 4-4 tie, along strict party lines, failing to adopt the recommendation of the Hearing Officer, and ordered the complaints dismissed. The complaint against O'Connor and his ward organization was one of eight that the Cook County Republican Party appealed all the way to the Illinois Supreme Court. On January 23, 2009, the Illinois Supreme Court unanimously ordered the Illinois appellate court to conduct a judicial review of the Board's dismissals of the complaints. On December 19, 2009, the First District of the Illinois appellate court affirmed the Illinois State Board of Elections' dismissal of the complaints.

O'Connor was defeated in his challenge to Republican incumbent Jack O'Malley in a campaign for Cook County State's Attorney in the general election of November 3, 1992, with O'Malley garnering 62% of the vote to O'Connor's 38%. O'Connor lost to O'Malley in O'Connor's own ward, 8,516 to 9,363.

O'Connor was defeated by Cecil Partee in a four-way race for the Democratic nomination for Cook County State's Attorney in the Democratic primary of March 20, 1990, with Partee garnering 49% of the vote to O'Connor's 37.5%.

O'Connor was first elected alderman for the 40th Ward in 1983. He was subsequently reelected eight times, in 1987, 1991, 1995, 1999, 2003, 2007, 2011, and 2015. In 2019, he was denied a tenth term on the City Council, being unseated by challenger Andre Vasquez.

In his first term a federal grand jury investigated O'Connor for providing, in late 1983 and again in late 1984, year-end jobs on the Education Committee staff for fifteen persons, including his mother-in-law, his brother-in-law, his sister-in-law, wives of two former members of his law firm, and the wife of a former staff aide. Some of those hired admitted they did not realize they were on the City payroll. "All in the Family" was a popular name for O'Connor's hiring practices, and O'Connor became known as the "City Hall Santa." O'Connor compared his hiring practices to those of Britain's royal family. When asked at a City Hall news conference if the practice amounted to nepotism, O'Connor said: "Absolutely. I think nepotism is a system that has been around a long time. It has worked very well in England. I don't think it's been much more of a problem here."

O'Connor graduated from Loyola University of Chicago School of Law in 1979. Fresh from law school, O'Connor successfully sued the city for back pay for his father after Mayor Jane Byrne fired him.

Patrick J. O'Connor (born 1955) is a former Chicago politician. He is the former alderman in Chicago's City Council representing the 40th Ward on the North Side of the city. He was first elected in 1983 at age 28. His tenure ended in May 2019 after his loss to challenger Andre Vasquez in the 2019 Chicago aldermanic elections. O'Connor was an unsuccessful candidate in the Democratic Party primary election for Illinois's 5th congressional district special election, 2009.

O'Connor is married to Barbara O'Connor, a real estate broker. In the last decade Barbara has built a successful business selling houses and condos, many of which could not have been built without zoning changes enacted by the city council. Barbara sold more than $22 million worth of houses and condos in the 40th ward after the projects were enabled by Alderman O'Connor.
