You shouldn’t believe everything you hear online. A cellphone video circulated on social media all weekend, claiming Chicago’s mayor deployed a convoy of the road crew’s plow trucks—used to spread salt during snowstorms—to block ICE agents’ vehicles from entering the city.

The poster filmed this video from a moving car. The footage shows a row of parked International trucks bearing the Chicago Department of Streets and Sanitation seal and painted light blue. A man’s voice points out the pun: salt is normally used to melt ice on roads in the wintertime. The compelling imagery and amusing audio helped the video go viral. The only problem? It isn’t true.

The truth about Chicago’s plow/salt trucks summer deployment

No, the video isn’t AI slop. There was a row of trucks parked along Grant Park. But a Chicago spokesperson explained the Department of Streets and Sanitation, “deployed salt trucks to support public safety efforts related to a planned protest and the Taste of Chicago. This is a routine practice.”

Mayor Brandon Johnson isn’t preventing ICE or the National Guard from entering the city. The trucks aren’t forming a slow-moving blockade on I-294, I-94, or the Edens Expressway—as some posts claim.

The protest in question was in response to President Trump musing about deploying National Guard troops to Chicago as part of his administration’s campaign against illegal immigration and crime. Thousands marched peacefully downtown on Saturday. The Pilsen Mexican Independence Day Parade also went without a hitch.

According to the Chicago Sun-Times, no National Guard troops have arrived in the city. There doesn’t appear to be any heightened immigration enforcement.
