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." Madigan stated that Paprocki had informed him earlier that he would be forbidden from taking the sacrament if he permitted the House to debate and vote on the measure, but that he chose to do so.

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. Despite the opposition and objections of the Village of Wilmette, the City of Evanston, the publicly operated Canal Shores Golf Course and numerous community organizations, 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. The parcel had been landlocked when the Keefe Family Trust purchased it.
