Narrative:

We were taxiing south on runway 18 (ord) making a left turn eastbound on the 9L-27R parallel taxiway. I felt the airplane slide to the left and the left main gear left the taxiway and bogged down. Ord ground control and our company were notified. Passengers were removed by mobil ramp and transported to terminal by bus. There was approximately 6 inches of wet snow accumulation and poor braking.
