America's Worst Mayor Tiffany Henyard is now under criminal investigation as feds probe restaurant and property management company she owns

The woman dubbed 'America's worst mayor' is reported to be under criminal investigation after being subpoenaed by the feds.

Dolton, Illinois Mayor Tiffany Henyard is facing claims of misusing funds, wrongful termination and covering up the sexual assault of a former employee. 

FBI agents served subpoenas on Friday at the Thornton Township Hall, where Henyard also works as township supervisor, reported FOX 32 Chicago.

The local news station obtained copies of the subpoenas and revealed the embattled mayor is the target of a growing criminal investigation.  

'It's very broad in scope. It's very broad in the number of people and entities they're asking for records on. So there must be some serious allegations of wrongdoing that they're trying to get to the bottom of,' former FBI agent Ross Rice told FOX 32.

'The mayor and the Township Supervisor, who are one and the same, appear to be the primary focus of the investigation.'

'Overall, it tells me that the investigation is expanding. It's not just focusing on the City of Dolton,' Rice said.

One subpoena is reported to focus entirely on Henyard, including a restaurant and a property management company she owns, as well as her political fund and the charity bearing her name. 

The subpoena seeks all records including personnel files, wage and tax statements, time and attendance, records of work performed, contracts, and checks written to 'cash.'

The second subpoena is said to request township records, including financial reports, budgets, payroll records, and ordinances covering credit card purchases, expense reimbursements, security details and use of vehicles.  

The Del Galdo Law Group is asking to withdraw from cases in which it represents Henyard and the village of Dolton, Illinois.

In a letter to Henyard and trustees, the firm said the village is approaching the point of becoming uninsurable. It faces millions of dollars in judgments from earlier cases and could potentially be required to shell out millions more in the coming months.

To add insult to injury, the firm has allegedly not been paid for its work.

'The Board recently voted to stop paying our legal bills,' reads the letter provided to DailyMail.com. 'We are, of course, not required to work for free and decline to do so.'

The firm announced that it would no longer be entering any appearances or defending newly filed cases and would withdraw from an additional 19 cases, effective May 8.

Five of the cases involve 'serious injury or death,' including two 'jail suicide by hanging cases' and two 'officer involved shooting wrongful death causes of action'.

'No one wants to represent the Village,' the firm continued.

'The Village already has a $33.5 million judgment against it that the previous administration and the Board ignored please to settle within policy limits, where the Village's best hope is that the jury verdict will be reversed on appeal.

'If that is unsuccessful, the Village will owe more than $20M in excess insurance policy limits on that case alone.'

According to the firm, Dolton 'is quickly approaching the point of being uninsurable' due to its immense debt.

In addition to her entanglement in the village's legal affairs, Henyard, 40, is the subject of 22 lawsuits regarding her conduct.

She faces a slew of accusations ranging from misusing funds while Dolton slides deeper into debt, to wrongful termination, to covering up sexual misconduct by a village employee.

Former Chicago Mayor Lori Lightfoot was tapped to investigate claims against Henyard by the village of Dolton.

Amid mounting tensions, dozens of residents rallied in nearby Calumet City on Saturday afternoon. One demonstrator held a poster proclaiming, 'Thornton Township belongs to us!' 

Longtime local barber Tyrone Isom Jr. hit Henyard with another lawsuit claiming the mayor's office improperly denied his permit to expand his business to a new commercial venue in the Chicago suburb of Dolton.

Isom says he purchased a property on Sibley Road with the intent to establish a new branch of his business, Elite Clientele LLC, but his venture was blocked on the whims of Henyard, 40.

The businessman said the zoning for the property is 'commercial' and allows a barber shop so he fixed it up ready to go - but 'got the run around' from the Village of Dolton as they blocked his permit.

Keith Freeman, a senior administrator for both the Village of Dolton and Thornton Township, pleaded not guilty to bankruptcy charges on Wednesday.

He has been accused of hiding his Dolton income in bankruptcy proceedings and underreporting his income by $95,000 last year.

His appearance in federal court came just one day after he was sued alongside Henyard by a Dolton property owner who said he was unjustly denied a business license.
