(CNN) Chance the Rapper donned a red Chicago Teachers Union sweatshirt while hosting "Saturday Night Live" in a show of support to the teachers who have been on strike.

Chance the Rapper showed support for the Chicago teachers on strike by wearing a Chicago Teacher's Union Sweatshirt when he hosted "Saturday Night Live."

Chicago teachers have been on strike since October 17 demanding more support staff, higher raises and limits to class size. Chicago Public Schools is the third biggest school district in the country.

"To the teachers in Chicago, I know you guys are on strike right now. I fully support you," Chance said Saturday, adding the joke "I just wish that when I was in school my teachers had gone on a strike."

Chance, who is from Chicago, also rapped about the city's nickname "The Second City" and how he's a fan of all things in second place.

Michelle Gunderson, a public school teacher and trustee for the teacher's union, tweeted during SNL that the bargaining team was working but took a break to watch the rapper.
