At least 20 communities with large warehouses across the U.S. have become stealth targets for Immigration and Customs Enforcement’s $45-billion expansion of detention centers. Communities are objecting to mass detentions and raising concerns that the facilities could strain water supplies and other services while reducing local tax revenue. In many cases, mayors, county commissioners, governors and members of Congress learned about ICE’s ambitions only after the agency bought or leased space for detainees. That's led to shock and frustration even in areas that have backed President Donald Trump. This is happening as public support for ICE and Trump's immigration crackdown sags.
