DHS leader: fewer than 1,000 separations

WASHINGTON -- A top Trump administration official said Thursday the number of family separations at the border has fallen since last summer's zero-tolerance policy, and they are done only for compelling reasons.

Acting Homeland Security Secretary Kevin McAleenan said fewer than 1,000 children have been separated from families out of 450,000 family groups crossing the border since October. He said they are separated because of health and safety concerns, among other reasons.

"The vast majority" of families are kept together, he said.

That tally does not include children who come with older siblings, or aunts and uncles and grandparents and are separated under longstanding policy meant to guard against human trafficking. McAleenan said Congress would need to amend laws to allow border officers more discretion in order to keep those groups together.

McAleenan was speaking Thursday before the House Oversight Committee investigating border problems. His testimony comes amid a growing outcry over the treatment of migrants at the border, an internal investigation into Border Patrol agents who posted crude and mocking posts in a secret Facebook group and the move this week to effectively end asylum on the U.S.-Mexico border.

Lawmakers mostly questioned McAleenan about the policy leading to the separation of more than 2,700 children from parents last year. A watchdog reporter later found thousands more may have been separated. Democrats and Republicans on the committee also traded barbs over emergency border funding and the moment the massive numbers of border crossings became a crisis.

"As I have testified and warned publicly, dozens of times this year and last, we are facing an unprecedented crisis at the border," McAleenan told the committee.

U.S. Customs and Border Protection officials have encountered more than 800,000 migrants crossing the border from Mexico. Over 450,000 were families.

"Combined, that means over 300,000 children have entered our custody since October 1st," he said.

Oversight Committee chairman Elijah Cummings, a Maryland Democrat, said McAleenan was an architect of the family separations. McAleenan wrongly called reports of filthy, overcrowded border facilities "unsubstantiated," Cummings said.

"The administration wants to blame Democrats for this crisis, but it is the Trump administration's own policies that are causing these problems," Cummings said.

The number of border crossings dropped last month amid hot weather and a crackdown by Mexico on migrants to its southern border.

McAleenan said facilities are less crowded, especially for children who are only supposed to be held in border holding stations for 72 hours. Delays along the entire immigration system have forced migrants to wait in crowded border facilities not meant to hold people for more than a few days.
