UNITED NEWS INTERNATIONAL (UNI) — Thousands of people marched in cities across the country to protest the Trump administration’s immigration policies.

On June 30, hundreds of thousands of protesters attended more than 700 marches in cities from Los Angeles to Washington, D.C., to New York City.

Known as the “Families Belong Together” protests, the marches were organized by dozens of progressive groups, including the ACLU, Planned Parenthood, Move On and the Women’s March.

The demonstrators demanded that the Trump administration end family separations and detentions and reverse its “zero tolerance” policy on immigration.

Trump took to Twitter to praise Customs and Immigration Enforcement officers, telling them they’re doing “a fantastic job” and not to “lose [their] spirit.”

The marches came two days after nearly 600 people were arrested on Capitol Hill after they flooded a U.S. Senate building to protest President Donald Trump’s immigration policies.
