The Mexican independence celebration "El Grito Chicago," originally scheduled for Sept. 13 and 14 at Grant Park in downtown Chicago, has been postponed due to possible ICE activity and the potential deployment of the National Guard.

After weeks of warnings Chicago could be the next US city to see National Guard troops rolling through its streets, local leaders are preparing – from the governor bracing for a court fight to parade planners postponing – even while it’s still not clear troops will show up.
