Arne Duncan, who served as the secretary of education in the Obama administration, is leaving the door open for running against Democratic Chicago Mayor Lori Lightfoot in 2023.

Duncan, who was once the head of Chicago Public Schools, said he has been urged to run for mayor by business leaders, according to the Chicago Sun-Times.

"I will absolutely look at this as we go forward long-term," Duncan said. "If I think I can make a bigger difference in another seat, I’ll absolutely look at that."

"I’m not running for anything right now," Duncan clarified. "But I am deeply concerned about where we are as a city. Nobody feels like we’re in a good place. … Our city’s in a really tough spot. I’ve lived here all my life. I love this city. As I talk to folks, they’re probably more concerned now than at any time that I can remember."

"You just want to build a really strong team to work on these really hard problems together," Duncan also said. "Have everybody on the same page, being honest and working through these tough issues together. That’s what I’d love to see happen here in the city."
