controversy engulfing Chicago public schools reached city Hall today with all people demanding school board members answer questions about the financial crisis facing CPS that led to a fiery exchange between the mayor and aldermen.

Gilbert, Villegas.

>> I urge you and your authority as the person who's appointed the board members as well as the new board members.

>> You want me to exercise my authority.

Absolutely.

Size York already.

>> Oh, boy.

W T Tw News reporter Heather Sharon joins us now to break down another tense day at City Hall.

Heather, what prompted that exchange?

>> and he gave us was one of 41 alderman to sign onto a letter demanding that the current and members for CPS coming to a special city council meeting today at City Hall and answer questions about the district's future and whether they would fire Co Pedro Martinez and whether they would take out a high interest, short-term loan shore up the district's finances.

Now, no board members showed up today and Alderman Villegas told me that that was because he had reached an agreement with Alderman, Jeanette Taylor Johnson's chair of the Education Committee to hold a education committee meeting next Friday.

But as you heard in an exchange aldermen, Villegas thought the mayor had committed to sort of encouraging if not ordering those board members to come to the city Council meeting.

And that is far from the case after today's City Council meeting after that exchange, we heard from the city's top lawyer, Mary Richardson, Larry, saying the city council does not have the authority to subpoena board members to appear in front of them.

And that is something mayor says he is not willing to negotiate on.

>> Okay.

And Heather.

In other news, the mayor said today he will not veto an ordinance passed last month designed to stop him from scrapping shot spotter.

Let's listen to what he told you about why he reversed course.

>> What it did tempted to do is to give procurement authority to a separate body, which is illegal.

You know, the procurement rest within the executive branch to take that outside.

The executive branch is a dangerous precedent because could you imagine if each entity had the ability regardless of the executive authority to just going to procurement with any entity.

I mean, you could have.

You could have a second term with Donald Trump and God knows we don't want that.

>> So Heather, where does this leave the issue?

In limbo?

This ordinance?

The mayor says it's illegal has been passed, but it hasn't been vetoed.

And the mayor has said that it will not be enforced.

>> It now ends up in the lap of the older people who feel strongly that Chicago needs a gunshot detection system.

They say they are willing to sue the mayor and the city and ask a judge to force him to follow this ordinance that would decades of contracting law.

And it's not clear that the city council can have a lawyer that will take the case and that they will find a sympathetic judge.

But is an indication of just how deeply this his son, dirt relations between Johnson and some older people.

An indication today that we saw that 9 older people voted against even ending the meeting at the mayor's request.

Things are very tense here at City Hall.

>> To say the least, there are a little tense at CPS is welcoming back to that for just a minute.

Other what is your sort of analysis?

What is your take on this back and forth and the argument over whether or not tips can the city can be detached or whether I'm a lot more to money can be given to CBS.

>> Well, I think there are real questions about the legality of the proposal made today by the teachers union.

It would essentially strip funding from projects that are already approved and have the gun, at least the initial planning.

I believe that violates state law.

The other issue with what we heard CEO Martinez proposed today is would be truly a massive amount of money from the city's to strict going into the school district last year.

The school district got 97 million dollars which helped.

It's about which help to balance its budget back then.

And if we're talking about somewhere in the neighborhood of 400 million dollars, that is a massive change.

And it also threatens to make the city's budget crisis work because the city for as long as I've been on this beat, has relied also get surplus to keep its budget out of the All right.

Questions about if there's enough go
