The former chairman of the Illinois Gaming Board filed suit against the state Executive Ethics Commission.

The commission found that he engaged in unlawful political activity while a board member.

The former chairman argued that state law does not bar contributions by members of state boards and that any such ban on contributions is a violation of the First Amendment.

The investigation began when the chairman contributed to a candidate for state senate and his spouse signed the check.

The Inspector General deemed suspicious 30 other instances of political donations and campaign contributions made while the chairman was on the gaming board.

While acknowledging that spouses of gaming board members are permitted to make contributions, the inspector general looked to the spouse’s history of contributing and to the number of contributions that were to the same committees her husband previously supported.
