An electronic petition has been organized at Change.org by Ellen Ripley. A lot of familiar faculty and friends of the City Colleges have already signed.
The City Colleges of Chicago is a public organization that serves everyone in the city, either directly or indirectly. Everyone who supports the cause is welcome to sign.
You can sign the petition here. The organizer of the petition has set a goal of 500 signatures. Since the petition was started 18 hours ago at the time of this writing (approximately 7:00pm on June 22), the petition has acquired 227 signers.
