House Speaker Michael Madigan on Tuesday issued a warning to Democratic lawmakers: Keep your relationships with staff members “strictly professional,” otherwise he will “personally get involved to put an end to it.”

Madigan delivered the directive during a closed-door meeting with members of his caucus, a week after he released a partial list of sexual harassment, discrimination and retaliation complaints he says his office has investigated in recent years. Among that summary were two instances in which legislators made inappropriate sexual comments to staff members.

State House Speaker Mike Madigan on Tuesday delivered some strong words to Democratic House members, warning them that if he hears of any sexual harassment complaints against them “I will personally get involved to put an end to it.”

But the woman who put the powerful Southwest Side Democrat under the microscope with  allegations that she was sexually harassed by a member his political organization was not impressed, saying Madigan sounds more worried about his own political neck than the safety of women.

A massive project to expand O’Hare International Airport was introduced with great fanfare last week, only to then hit some turbulence. American Airlines says it was left out of the negotiations and that the city is playing favorites with its top rival, United. Could this dispute ground the entire deal?

American Airlines says it is exploring options, including a counter deal the company has put on the table. Both American, United and city officials are meeting with aldermen Tuesday and throughout the week. We’ve been told the airlines are heavily lobbied up because the plan is currently before City Council as it looks to hold hearings, debate and ultimately, a vote.

The CTA this week will start knocking down buildings in the Lakeview neighborhood to make way for the controversial “flyover,” an elevated bypass that agency officials say will cut down delays along a congested stretch of public transit on the North Side.

The demolition begins more than a year before the city plans to break ground on the flyover, which aims to unclog the bottleneck of Red, Brown and Purple Line trains that flow in and out of the Belmont Avenue station.

Chicago Teachers Union members and unionized graduate employees from UIC marched downtown on Tuesday in solidarity with striking graduate and teaching assistants at the University of Illinois, who have entered their second week of a work stoppage on the Champaign campus.

Yesterday, the city of Chicago filed a federal lawsuit against the “big three” pharmaceutical distributors. The lawsuit claims the companies have practiced “unfettered and unlawful distribution of opioids into the city.”

The defendants are Conshohocken, Pa.-based AmerisourceBergen Drug, Dublin, Ohio-based Cardinal Health and San Francisco-based McKesson. Together, they account for approximately 90 percent of all revenues from prescription drug distribution in the U.S., according to the city.

We’ve said it before. We’ll say it again.

The taxpayers should not be writing blank checks to townships.

Body cameras will not be issued to Peoria police officers until at least mid-summer, the interim police chief said this week.

But Lorien Marion, who was recently tapped to head the Peoria Police Department, said the delay is only from mid-spring to mid-summer. The department, he reiterated, will have body cameras soon. He did say the delay would allow Peoria to examine cheaper ways to store the footage.
