As families around the country celebrated Father’s Day, immigration activists in Texas on Sunday held a march and vigil to draw attention to recent separations of immigrant children from their parents at the U.S.-Mexico border.

The demonstration was sponsored by the Families Belong Together coalition, a group of organizations advocating for immigrant rights that includes the National Domestic Workers Alliance, the American Civil Liberties Union, People’s Action, United We Dream, America’s Voice, the Women’s Refugee Commission and Faith in Action.
