The good news is that just under 3,000 of the 4,000 children separated from their families by ex-President Trump’s “zero tolerance” immigration policy at the southern U.S. border have been reunited. That policy was lambasted as cruel and inhumane by critics. It has taken years for government officials to reconnect relatives with their young children.

Nearly 1,000 children still need to be reunited with their relatives. It is the second anniversary of the task force created to help with the reunifications. Many of those kids are Central American migrants who were separated from their parents at the border and placed in detention centers. That method was part of the Trump administration’s hardline approach to immigration and was meant to deter millions of migrants from seeking asylum in the US during his term in the White House.

“We understand that our critical work is not finished,” DHS Secretary Alejandro Mayorkas said in a statement. “We remain steadfast in our commitment to fulfill President Biden’s pledge to reunify all children who were separated from their families under the ‘zero-tolerance’ policy to the greatest extent possible, and we continue to work diligently to incorporate the foundational principle of family unity in our policies and operations.”

“We have made significant progress toward reunifying families and providing them with necessary services and support,” the Dept of Homeland Security said. “This critical work will continue until all separated families that can be found have been provided the opportunity to reunify.”
