Ald. Raymond Lopez (15), one of Mayor Lori Lightfoot’s loudest critics on the City Council, on Wednesday officially announced he plans to run for mayor in 2023. During his official campaign launch at The Plant in Back of the Yard, Lopez said he plans to “focus on safety, rebuilding our economy and supporting our first responders and city employees that serve the taxpayers of the city of Chicago.”
