(The Center Square) – The mayor of Chicago testified during a congressional hearing Wednesday that his city is safer because of its Welcoming City ordinance. “Any actions that amplify fears of deportations make Chicago more dangerous. Those fears cause witnesses and victims to avoid cooperating with police,” Mayor Brandon Johnson said. Johnson joined mayors from Boston, Denver and New York City before the House Committee on Oversight and Government Reform. Committee Chairman James Comer, R-Kentucky, said sanctuary policies risk the safety of federal agents and the public.
