Police arrested about 100 clergy demonstrating against immigration enforcement at Minnesota’s largest airport Friday, and several thousand gathered in downtown Minneapolis despite Arctic temperatures to protest the Trump administration’s crackdown.

The protests are part of a broader movement against Donald Trump’s increased immigration enforcement across the state, with labor unions, progressive organizations and clergy urging Minnesotans to stay away from work, school and even shops.

The faith leaders gathered at the airport to protest deportation flights and urge airlines to call for an end to to what the Department of Homeland Security has called its largest-ever immigration enforcement operation.
