Chicago Democratic Reps. John Fritchey and LaShawn Ford made a public plea to Gov. Pat Quinn on Sunday to deploy troops.
The request comes amid a recent surge in violent crime, including a night last week that saw seven people killed and 18 wounded, mostly by gunfire.
Fritchey says Chicago has had 113 homicide victims this year. He says the police department has done a commendable job, but its resources are stretched thin.
Chicago Police Supt. Jody Weis says he appreciates the lawmakers' frustration and willingness to help, but doubts the National Guard is the best answer.
A message left for Quinn wasn't returned Sunday.
