Illinois State Representative Margaret Croke is facing criticism after sending an email that listed detailed information about vehicles believed to belong to Immigration and Customs Enforcement (ICE) agents operating in Chicago.

The email, distributed Friday under the subject line “Updated List of ICE Vehicles Seen Today,” included the make, model, color, and partial license plate numbers of several vehicles allegedly linked to ICE personnel in the area.

In the message, Croke urged recipients to report what she described as “suspicious activity” to local hotlines.

She wrote that ICE operations are “unlawful and undemocratic” and provided resources for individuals in the country illegally to contact attorneys and social service organizations.

The email also encouraged residents to “record and share” information about potential ICE vehicles in order to “protect someone from either being picked up off the street or unnecessarily and forcibly handled.”

Critics quickly denounced the move, arguing it endangered federal agents and obstructed lawful immigration enforcement.

The popular X account Libs of TikTok posted screenshots of the email, accusing Croke of “putting a target on agents’ backs” and assisting illegal aliens in avoiding arrest.

“She’s putting a target on agents’ backs and helping illegals evade arrest. This is absolutely disgraceful. CHARGE HER,” the account wrote in a post tagging the Department of Homeland Security and ICE.

Federal law prohibits disclosing personally identifying information of law enforcement officers engaged in undercover or sensitive operations.

Several former federal prosecutors and law enforcement officials have expressed concern that Croke’s email could violate those statutes.

While Croke’s office has not issued a formal statement, legal experts said such disclosures could interfere with federal operations and expose agents to potential harm.

The Department of Homeland Security has not commented publicly on whether it plans to investigate the incident.

This controversy follows similar actions in Chicago led by former Mayor Lori Lightfoot, who recently announced the creation of a nonprofit called “The ICE Accountability Project.”

The organization, according to Lightfoot, is intended to document and publicize the actions of federal immigration agents in so-called sanctuary jurisdictions.

Lightfoot, a former federal prosecutor, has defended her initiative as a transparency effort.

She said it was designed to ensure public oversight of federal immigration enforcement, which she has criticized as overly aggressive.

However, Attorney General Pam Bondi said on Fox News that Lightfoot’s actions could violate federal law protecting the identities of agents.

“She will be getting a letter from us tomorrow to preserve anything she has done as well, to make sure that she’s not violating the law. It appears she is,” Bondi said.

“You cannot disclose the identity of a federal agent — where they live, anything that could harm them.”

Bondi’s office has not yet commented on whether similar legal concerns apply to Croke’s email, but she confirmed that such disclosures are being closely reviewed by federal authorities.

According to law enforcement data, incidents of threats and assaults on federal officers have sharply increased in recent years.

Officials say these attacks have grown particularly frequent in areas with “sanctuary city” policies, which limit cooperation between local police and federal immigration authorities.

Federal sources have not confirmed whether any of the vehicles listed in Croke’s email were actually connected to ICE agents.

An internal Department of Homeland Security review is expected to determine if operational security was compromised.
