Immigration System At The 'Breaking Point,' Homeland Security Official Warns

Immigration authorities are expressing alarm about the growing number of migrants crossing the Southern border.

On two days this week, federal agents apprehended more than 4,000 migrants crossing the border — the highest daily total recorded in 15 years, according to a senior official with Customs and Border Protection.

"The breaking point has arrived," said CBP Commissioner Kevin McAleenan on Wednesday in El Paso, Texas.

"CBP is facing an unprecedented humanitarian and border security crisis all along our Southwest Border — and nowhere has that crisis manifested more acutely than here in El Paso," McAleenan said.

As the weather warms up, immigration authorities warn that the flow of migrants crossing will continue to grow. Federal agents are on pace to apprehend or encounter more than 100,000 migrants in March — the largest monthly total in more than a decade.
