Biden's task force finds more than 3,900 children separated from families at border under Trump

More than 3,900 children were separated from their families along the border after the Trump administration launched its "zero-tolerance policy," a new report says.

The Biden administration has determined that more than 3,900 children were separated from their families along the Southwest border after the Trump administration launched its controversial "zero-tolerance policy," and -- while several hundred children were returned to their home countries -- fewer than 60 families are now in the process of being reunited, sources familiar with a new report from the Biden team told ABC News. The report has yet to be released publicly, but its findings mark an official assessment from the Department of Homeland Security and other federal agencies of how many children were actually impacted when the Trump administration decided to take what many considered drastic steps to fight illegal immigration. The report's findings also reflect how difficult and challenging it is to repair the damage that was done under the previous administration, a Homeland Security official said. The report -- expected to be made public in the coming days -- is an initial progress review from the administration's Family Reunification Task Force, which Biden created in February. It is chaired by Homeland Security Secretary Alejandro Mayorkas. The task force determined that of the more than 3,900 children separated between July 2017 and January 2021, nearly 400 of them have already been repatriated to their country of origin. And for those children still inside the United States without their parents, Biden's task force is offering their families an option to come to the United States. It has approved a total of 62 family members for entry into the country -- an initial group that includes four families already reunited, according to the task force's report.
