John J. Cullerton (born October 28, 1948) is an American politician who served as a Democratic member of the Illinois Senate, representing the 6th district from his appointment in 1991 to 2020.

[12] In May 2017, Cullerton intervened in a land dispute outside of his district when he advocated, on behalf of the Keefe Family Trust, to pave over a section of publicly owned wetland to build a 28 foot long driveway, which would require killing approximately 48 mature trees in a small old-growth forest.

[13] Despite the opposition and objections of the Village of Wilmette, the City of Evanston,[14] the publicly operated Canal Shores Golf Course[15][16] and numerous community organizations,[17][18][19] Cullerton met with local officials on multiple occasions to argue in favor of a driveway to access a landlocked parcel so the Keefe Family Trust could build a subdivision of three houses.

Fagel Haber merged with Thompson Coburn LLP in 2007, and Cullerton continues as a partner,[21] practicing in the areas of government relations, zoning, licensing, real estate tax assessment, and nonprofit law.

[23] On June 6, 2019, Bishop Thomas Paprocki issued a decree officially barring Illinois House Speaker Michael Madigan and Senate President John Cullerton from presenting themselves to receive the Eucharist on account of their role in Passing the Reproductive Health Act, which removes spousal consent and waiting periods for abortions.

While singling out Madigan and Cullerton specifically, Paprocki also asked that other legislators who voted for the bill not present themselves for Communion either, stating that they had "cooperated in evil and committed grave sin."
