Led by U.S. military veterans, Global Response Management is staffed by volunteers primarily from the U.S. and paid asylum seekers who were medical professionals in their homelands. The group has treated thousands of migrants over the past year at two clinics in Matamoros, including one inside the camp. (AP Photo/Eric Gay), APTOPIX
