Illinois Gov. J.B. Pritzker signed legislation prohibiting dark money contributions to judicial candidates.

Effective immediately, Senate Bill 536 prohibits a political committee established to support a state judicial candidate from accepting contributions from any out-of-state person and from any entity that does not disclose the identity of all donors to the entity.

The bill also prohibits any entity that does not disclose the identity of all donors from financing a distribution or broadcast of campaign materials prepared by the candidate, his or her campaign committee, or designated agents.

The bill also increases the threshold for which contributions to a conduit must be itemized from $500 to $1,000.
