Homeland Security Alejandro Mayorkas on Sunday defended inspections at the U.S.-Mexico border, but he struggled to explain how a truck got through a checkpoint packed with dozens of migrants who died in the Texas heat.
Mr. Mayorkas, touring the morning talk shows, said a criminal investigation is underway and described smuggling organizations as highly sophisticated.
“These are very sophisticated transnational criminal organizations,” Mr. Mayorkas told CBS’ “Face the Nation.” “Can a truck get through — through sophisticated means? Sometimes, yes.”
More than 50 migrants died in the truck found Monday on a country road in San Antonio.
