What the Evidence Shows
The claim asserts that the Trump administration has located and recovered 10,000 migrant children who were lost during the Biden administration as part of a mission to reunite them with their families. This claim conflates several issues and misrepresents the facts.
First, the notion that thousands of migrant children were 'lost' or 'left behind' during the Biden administration is widely disputed by experts and fact-checkers. The figure of over 300,000 'missing' children often cited in political rhetoric refers to children for whom paperwork or follow-up contact was incomplete, not children who were physically lost or abducted.apnews.comapnews.comFACT FOCUS: Claims that more than 300,000 migrant children are missing lack...

Second, there is no verified evidence that the Trump administration undertook or completed an operation to locate and recover 10,000 such children during the Biden administration's tenure. Reports indicate that welfare checks on migrant children have been conducted by Homeland Security under both administrations, but these efforts do not support claims of mass recovery of lost children.cbsnews.comcbsnews.comTrump claims Biden lost track of over 300,000 migrant children.

Third, fact-checking organizations have found that describing these children as 'missing' is misleading because many are safely living with family members or sponsors; the issue is more accurately described as a paperwork or tracking challenge rather than a disappearance crisis. Finally, no credible source confirms President Trump or his administration recovered such a specific number of children lost during Biden's term.
The claim appears to be a political narrative without factual support. Therefore, the claim is false as it misrepresents the situation regarding migrant children and lacks evidence for the alleged recovery operation.
