Goodbye, Columbus Day. CPS ends the holiday in favor of Indigenous Peoples Day — and parade organizers call it ‘a slap in the face.’

Columbus Day will no longer be observed in Chicago Public Schools — and the group behind the city’s annual Columbus Day parade is already pushing to reverse that decision.

“This is a slap in the face of the more than 500,000 Italian Americans in Chicago, and the 135 million Italian Americans worldwide,” said Sergio Giangrande, president of the Joint Civic Committee of Italian Americans, in a statement provided to the Tribune.

Giangrande said the group “is challenging CPS’s decision and has mounted a campaign to reverse this action.”

Following similar moves in other school districts and cities, the Chicago Board of Education voted Wednesday to drop Columbus’ name from the October school holiday in favor of an observance of Indigenous Peoples Day.
