Frida Ghitis: Tragic photo is a moral stain on Trump's America

Angie Valeria had not celebrated her second birthday when she drowned on Sunday, grasping her father as they tried to reach the United States. The picture of tiny Valeria, face down, with her tiny arm still around her dead father's neck, has become the heartbreaking symbol of the Trump administration's cruel -- and failing -- policies at the southern border. Valeria and her father, Oscar Alberto Ramirez, are more than a statistic because we have their picture. But they are not an anomaly.
