U.S. Rep. Luis Gutierrez announces Wednesday, Sept. 12, 2018 that he will not run for Chicago mayor. (Chicago Tonight)

There may soon be tidal waves in the race for Chicago mayor, should Cook County Board President Toni Preckwinkle run, or should County Commissioner Jesus “Chuy” Garcia take a second shot at the city’s top job.

One of the most intriguing congressional districts in the country, Illinois' 4th Congressional District includes parts of Chicago's Logan Square neighborhood, Melrose Park, Brookfield, Cicero and Brighton Park. Joining "Chicago Tonight" to talk about his vision for the district is Javier Salas. Congressman Luis Gutiérrez declined our invitation.
