ICE federal agents pulled over a man and said he had swerved towards them while they were conducting a stop on the side of the road.

Millcreek Mayor Jeff Silvestrini emailed the U.S. Immigration and Customs Enforcement (ICE) expressing his concerns over what he called “unprofessional and perhaps criminal conduct” from ICE agents.

U.S. immigration agents made “demonstrably false” statements to local police during a traffic stop last month, potentially committing a crime in the process, a Utah mayor alleged in an email urging the agency to investigate its own officers.
