More than 1,600 individual donations were made to Chicago’s elected city officials and Ward Organizations in the month of June, making it one of the biggest fundraising months since the 2015 election.

Mayor Rahm Emanuel alone brought in approximately $525,700 in individual donations. A significant number of those donations, about 15, came from lawyers with Kirkland & Ellis.

A big chunk of that money, about $161,700, came in the form of three checks of $53,900, the maximum allowable amount a political action committee can give to a candidate in one election cycle. Those donors are all trade labor unions: the Chicagoland Operators Joint Labor-Management PAC, Engineers Political Education Committee, and the International Union of Operating Engineers Local 399.
