Officials with Chicago Public Schools claimed U.S. Immigration and Customs Enforcement agents were seen at Hamline Elementary School. The Secret Service said special agents were investigating a threat.

Fearing federal agents asking to search a Chicago elementary school Friday morning were from Immigration and Customs Enforcement, school officials denied them entry. But it turned out they were US Secret Service agents pursuing an investigation.

Sources said the Secret Service was investigating an online threat that a Hamline student made against President Trump following the U.S. ban on TikTok.

The agents turned out to be unrelated to immigration, officials said hours later. They were from the Secret Service, investigating a threat.

There has been no communication between ICE and the Genesee County Sheriff's Office regarding immigration enforcement, Sheriff Chris Swanson said.

Despite earlier reports that ICE agents tried to enter a Chicago elementary school Friday, the agency says it wasn't them. So what exactly happened?

The Trump administration intensified efforts to crack down on illegal immigration, making U.S. Immigration and Customs Enforcement (ICE) a central focus.

Nearly 1,000 people were arrested by federal agencies in a blitz to enforce immigrations policies across the United States, according to multiple reports.

Chicago Public Schools prevented federal officers from from going into an elementary school on Chicago’s Southwest Side Friday and talking to students, according to school officials.

A recent move by Trump allows immigration authorities to conduct raids at schools. Multiple school districts have pledged to complicate the efforts.

The decision to allow law enforcement officers to use facilities at Buckley Space Force Base in Aurora, Colo., plunges the U.S. military deeper into President Trump’s order to secure the southwestern border.
