The Chicago police superintendent fired by Rahm Emanuel said that he's running against the mayor to bring "legitimacy" back to his city's government.

Emanuel was called on to resign after he was accused of covering up the 2014 shooting of 17-year-old Laquan McDonald.

He was also accused of burying a tape of the shooting so that he could help secure his re-election.

"The cover-up of [McDonald's] case happened exclusively in City Hall," McCarthy said on "The Story with Martha MacCallum."

McCarthy said that the answer to issues facing Chicago like crime, lack of education and tax hikes is "legitimacy in government."

"If anybody ever ran a business the way that City Hall is run here in Chicago which is about political bullying, lying, pay-for-play, corruption, taking care of your friends ... you'd be out of business in a heartbeat."

He added that he was accountable for the officers involved in McDonald's shooting, but that he didn't have the authority to discipline them.

Emanuel initially defended McCarthy and Officer Jason Van Dyke after the incident, but ultimately fired McCarthy.

McCarthy has argued that the Chicago City Council voted to quickly pay McDonald's family millions of dollars.

He also said his mayoral run is "absolutely" not what some have called a "revenge move."

"I have adopted this city, and this city has adopted me," he said.
