Immigrants across the U.S. skip work, school in anti-Trump protest

DETROIT/SAN DIEGO (Reuters) - Businesses shut their doors, students skipped class and thousands of demonstrators took to the streets in cities across the United States on Thursday to protest President Donald Trump's immigration policies.

Activists called "A Day Without Immigrants" to highlight the importance of the foreign-born, who account for 13 percent of the U.S. population, or more than 40 million naturalized American citizens.

Trump campaigned against the estimated 12 million illegal immigrants, playing on fears of violent crime while promising to build a wall on the U.S.-Mexican border and stop potential terrorists from entering the country.

While the number of participants in Thursday's protests could not be determined, many sympathetic business owners closed shop and working-class immigrants forwent pay for the day.
