(CBS/AP) Former White House chief of staff Rahm Emanuel says he's preparing to run for mayor of Chicago.
Emanuel made the announcement in a video posted Sunday on his website, ChicagoforRahm.com.
The announcement has been expected since Emanuel resigned from President Barack Obama's staff Friday and headed immediately for Chicago.
Before working in the Obama administration, Emanuel served three terms as a Congressman for Chicago's North Side. He also worked as an adviser in the Clinton White House.
Before his tenure in Washington, Emanual worked at the Chicago investment bank Wasserstein Perella, and at Illinois Public Action.
"We need leadership that's tough enough to say no when it needs to be said, and smart enough to know what government should do - and also what it can't do," he says in the video.
Emanuel said in the video that he's launching a listening tour of Chicago's neighborhoods and will visit transit stops, grocery stores and hot dog stands.
One of the challenges facing him in a mayoral run is reconnecting with Chicago voters after his time in Washington.
