Chicago officials admitted they confused Secret Service agents who showed up at an elementary school to investigate a threat for ICE agents.

U.S. Immigration and Customs Enforcement agents were seen at a Chicago school Friday afternoon, according to officials with the city's public school district, though a spokesperson for the agency denied such an encounter.

The U.S. Secret Service told the I-Team they approached a South Side school Friday. Chicago Public Schools officials had initially said the agents were from U.S. Immigration and Customs Enforcement.
