I wouldn't ask other students to make comments to the admin if they do not think of it on their own. If they are asked why they are saying these things, it could end up looking very bad for you. It is not the responsibility of the students in the class to manage it. That is something for you, the student, his support staff, and the administration to figure out.

I wanted to add, that if students were complaining to you about the class, then that is a different situation and you should direct them to your department head or whoever else is in authority and dealing with this situation.
