A “pro-liberty” political action committee is challenging the state’s campaign-contribution limits, which it claims give an unfair advantage to legislative leaders who are exempt from them.

Liberty Justice Center – through its client, Illinois Liberty PAC – filed the suit challenging the constitutionality of the limits Tuesday in federal court. Dan Proft, chairman of Illinois Liberty PAC, said the law violates the equal protection clause of the 14th Amendment and the First Amendment.

“We don’t believe there should be two sets of rules when it comes to participation in the political arena in Illinois,” Proft said. “One set for party bosses of both political parties, another set for the other 13 million Illinoisans and the associated groups and organizations that want to take part in the political arena.”
