As expected, Illinois U.S. Congressman Danny Davis has formally announced he’s running for mayor of Chicago. Davis’ Sunday announcement came the day after former White House Chief of Staff Rahm Emanuel officially began his run to replace Chicago Mayor Richard Daley.

State Sen. James Meeks is expected to declare his candidacy later Sunday.

Davis was tapped earlier this month by a coalition of black leaders as their preferred candidate. They chose him over other finalists that included Meeks and former U.S. Sen. Carol Moseley Braun. Davis is a Democrat who has been in Congress since 1997. He previously served on the Cook County Board and the Chicago City Council.

In prepared remarks Saturday, Emanuel told supporters, “Chicago is where I was born, and where my children were raised. They are the fourth generation of my family to live here. Only the opportunity to help President Obama as his chief of staff could have pried me away from here. And only the opportunity to lead this city could have pried me away from the president’s side.”

Sunday evening, state Sen. James Meeks (D-Chicago) will officially start his candidacy at the University of Illinois at Chicago.

The list of expected candidates also includes City Clerk Miguel del Valle, ex-school board head Gery Chico and former U.S. Senator Carol Moseley Braun. Starting Monday morning, mayoral candidates can turn in their nominating petitions, including the required 12,500 signatures of registered Chicago voters.
