The Trump administration is considering a plan to separate parents from their children when families are caught entering the country illegally, according to officials who have been briefed on the plans. The forceful move is meant to discourage border crossings, but immigrant groups have denounced it as draconian and inhumane.

Under current policy, families are kept intact while awaiting a decision on whether they will be deported; they are either held in special family detention centers or released with a court date. The policy under discussion would send parents to adult detention facilities, while their children would be placed in shelters designed for juveniles or with a “sponsor,” who could be a relative in the United States, though the administration may also tighten rules on sponsors.

The policy is favored by the White House, and has been approved by Immigration and Customs Enforcement, according to three officials at the Department of Homeland Security and one at the White House who have all been briefed on the proposal but declined to be named because they were not authorized to discuss it publicly. The officials said that the new Homeland Security secretary, Kirstjen Nielsen, who has final approval power, has yet to sign off on the proposal.

The debate comes as the administration faces an influx of people crossing the southern United States border illegally. As soon as President Trump took office, the number of people caught crossing the border dropped sharply, a sign that far fewer people were even trying. Only 11,677 apprehensions were recorded in April, the lowest number in a least 17 years, according to Customs and Border Protection.
