Restaurants and other businesses around the United States shut their doors and thousands of demonstrators took to the streets of cities across the country in a walkout aimed at protesting U.S. President Donald Trump’s immigration policies.

The protest was prompted by Trump’s vows to crack down on illegal immigration and his executive order, which was put on hold by Federal Courts, that temporarily banned travel to the United States from seven Muslim-majority countries. Immigrant rights’ groups expressed alarm after federal raids last week in which more than 680 undocumented people were arrested.

Sympathy marches and rallies were also held in cities including Raleigh, North Carolina and Austin, Texas. Thousands joined demonstrations in Chicago and Detroit.

The protests were the latest in a series of actions by women’s groups, immigrant groups and other activists since Trump took office.
