The city of Denver has begun ejecting around 800 migrant families from shelters as it scales back on aid for illegal immigrants.

On Monday, about 140 families were booted out from temporary accommodations in Colorado’s capital, with the remaining 660 families expected to be removed over the next few weeks, according to city officials.

The sanctuary city has been struggling to stretch its limited resources to support the growing number of migrants in the city. Texas has transported thousands of migrants to sanctuary cities like Denver, to showcase the problems border states face when migrants flood their cities.
