The bill, HB 2040, was one of three measures to protect undocumented immigrants. The other two bills Pritzker signed prohibit local law enforcement officers from working with Immigration and Customs Enforcement offers to target migrants in the state and allow undocumented students to receive financial aid at public institutions.
