People who need help after the mass shooting at a Walmart in El Paso, Texas, may not seek it out because of their immigration status, authorities fear. “This is a concern,” Juliette Kayyem, a former assistant secretary of the Homeland Security Department, told CNN. “It’s clear there’s people who are not unifying with their family and that there are people they’re worried are injured that did not go to hospitals likely because of their immigration status.”
