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.
The fatalities marked one of the worst tragedies in border history and ignited a search for answers to the growing migrant death toll under President Biden.

“I think the facts are still under investigation, it’s a criminal case,” he told ABC’s “This Week.”
Mr. Mayorkas defended border inspections generally, saying officials stopped hundreds of vehicles and rescued more than 10,000 migrants in fiscal 2022 alone.
Yet the southern border has set records for chaos under Mr. Biden, who reversed several get-tough policies of the Trump administration.
Illegal migration quickly soared and has remained at a record pace in the 17 months since Inauguration Day, defying Mr. Biden’s insistence that the numbers were seasonal and nothing out of the ordinary.
Mr. Mayorkas on Sunday implored migrants not to make the perilous journey north.
“They put their lives, their life savings, in the hands of these exploitative organizations, these criminal organizations that do not care for their lives and only seek to make a profit,” Mr. Mayorkas told CBS.
