Venezuelan gang Tren de Aragua’s infestation of the Denver suburbs that came to represent the flimsy security at the southern border was made possible by city leaders who hired nonprofits to move migrants outside of Colorado’s capital,

At the same time that the ACLU of Colorado is investigating the Aurora Police Department's cooperation with U.S. Immigration and Customs Enforcement, Aurora's mayor is asking Denver's mayor for clarity on how and why the migrant population spread to Aurora.

"What has been happening is a lack of information. There are accusations that we're sending people [to Aurora], but let's clear this up because it's getting old."

Aurora, Colorado Mayor Mike Coffman, whose city became associated with issues involving illegal immigration this past election season, wrote in an op-ed Monday that Denver Mayor Mike Johnston placed migrants from the state's capital in his city.
