Of the more than 5,000 children who, court documents say, were separated from their parents under the previous administration’s zero-tolerance policy for unauthorized border crossers and those who presented themselves legally at ports of entry, about 180 children have yet to be reunited with their parents, according to VOA News, though the ACLU believes the numbers are actually much higher.

Within weeks of taking office in January 2021, President Biden created an interagency task force “to reunite children separated from their families at the United States-Mexico border;” however, the task force has struggled to find many of the parents who have been deported.

So far, Congress has not voted on any bills to help families that were separated under the zero-tolerance policy.
