CHICAGO (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.
      
Emanuel says 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.
      
Emanuel highlighted his ties to Chicago in the two-minute message, noting his three terms representing a North Side district in Congress.
