With tensions high over federal immigration enforcement, some state and local officials are pushing back against the Trump administration’s attempts to house thousands of detained immigrants in jails, converted warehouses and privately run facilities in their communities.

Federal officials have been scouting cities and counties across the U.S. for places to hold immigrants as they roll out a massive $45 billion expansion of detention facilities financed by President Donald Trump’s recent tax-cutting law.

The fatal shootings of Renee Good and Alex Pretti by immigration enforcement officers in Minneapolis have amplified an already intense spotlight on U.S. Immigration and Customs Enforcement, increasing scrutiny of its plans for new detention sites.

A proposed ICE facility just north of Richmond, Virginia, drew hundreds of people last week to a tense public hearing of the Hanover County Board of Supervisors.

“You want what’s happening in Minnesota to go down in our own backyard? Build that detention center here, and that’s exactly what will happen,” resident Kimberly Matthews told county officials.

As a prospective ICE detention site became public, elected officials in Kansas City, Missouri, scrambled to pass an ordinance aimed at blocking it. And mayors in Oklahoma City and Salt Lake City — after raising concerns about building permits — announced last week that property owners won’t be selling or leasing their facilities for immigration detention.

Meanwhile, legislatures in several Democratic-led states pressed forward with bills barring or discouraging ICE facilities. A New Mexico measure targets local government agreements to detain immigrants for ICE. A novel California proposal seeks to nudge companies running ICE facilities out of the state by imposing a 50% tax on their proceeds.

More than 75,000 immigrants were being detained by ICE as of mid-January, up from 40,000 when Trump took office a year earlier, according to federal data released Tuesday. In a little over a year, the number of detention facilities used by ICE more than doubled.

Trump’s administration now is taking steps to open more large-scale facilities. In January, ICE paid $102 million for a warehouse in Washington County, Maryland, $84 million for one in Berks County, Pennsylvania, and more than $70 million for one in Surprise, Arizona. It also solicited public comment on a proposed warehouse purchase in a flood plain in Chester, New York.
