ABC7's political reporter Craig Wall captured the tense moment in Chicago's Little Village neighborhood.
Twenty-fifth Alderman Byron Sigcho-Lopez was seen yelling at the governor about Mayor Brandon Johnson's proposed head tax on large companies.

But, as the campaign to vote for or against a budget that includes the head tax is heating up, the mayor is now willing to consider changing the terms of the tax.
The fight over Johnson's proposal to tax companies with more than 100 employees is getting louder, as Johnson scrambles for votes.
"We have a choice here, either corporations are going to pay or working class people are going to pay more in property taxes and grocery taxes," Chicago Teachers Union Political Director Hilario Dominguez said.
The Chicago Teachers Union is behind a campaign called Chicagoans Against Trump Cuts. CTU is spending money targeting wards where alders are against the head tax or undecided.
"The head tax is a job-crushing tax. It is a disincentive for businesses to grow in Chicago and bring new jobs to Chicago. If we want to address the fiscal deficits, we need to grow the pie, not shrink the pie," said Jack Lavin, Chicagoland Chamber of Commerce president and CEO.
Business and civic organizations are working just as hard to urge alders to vote "no" on a budget with a head tax. The mayor says money generated for the tax will pay for public safety, but the business community says it has already contributed.
"The Civic Committee and corporations throughout Chicago have raised $150 million for public safety. I think the business community has stepped up for public safety," Lavin said.
The money includes jobs for South and West Side residents. While outside interests wage their wars for and against the head tax, inside City Hall, the mayor and Budget Committee Chairman Ald. Jason Ervin are considering raising the monthly $21-per-employee tax for companies with 100 employees to 200.
"I think that, partially, the head count's been in conversation. The rate has been in conversation, so haven't landed that plane fully yet. But I know that those are ongoing conversations," Ervin said.
Others say adjustments to the tax won't change alders' minds until the mayor considers more cost savings.
"Why would we put ourselves in this position now, when the administration is just not really taking a look at the hard decisions around right-sizing government and creating efficiencies?" 36th Ward Ald. Gilbert Villegas said.
As the mayor and his allies continue to work on getting more support for the head tax, the hope is to vote on the budget possibly by next week. But, Ald Ervin says if the votes are not there, it will be pushed to December.
