Markueyn Mallin, the U.S. Secretary of Homeland Security, stated that President Donald Trump has tasked him with finding hundreds of thousands of migrant children who went missing during the Joe Biden administration while under government custody.
The secretary explained that approximately 146,000 children have been identified and found so far, but the fate of nearly 300,000 children remains unknown.
According to Mallin, investigations reveal that some of these children have become victims of sexual abuse, human trafficking, and other serious crimes.
The secretary described what happened during the Biden period as "at best, gross negligence, at worst, a crime."
The issue does not concern children who generally go missing in the U.S., but mostly unaccompanied minor migrant children who crossed the border.
Various reports from the U.S. government have noted that in recent years, hundreds of thousands of unaccompanied migrant children crossed the border and entered the custody of federal agencies. Later, they were handed over to guardians, relatives, or sponsor families. However, the government was later unable to track the whereabouts of some of them. Federal audit reports in 2024 revealed significant gaps in sponsor checks and subsequent monitoring mechanisms. The Trump administration claims that approximately 450,000 of these children went out of state custody.
Republicans put the responsibility directly on former President Joe Biden and his team. They accuse them of weakening border controls; not conducting adequate sponsor checks; failing to monitor the children’s subsequent fate; and not preventing human traffickers and fake sponsor networks from taking advantage of the situation.
However, Democrats and independent experts remind that the problem of unaccompanied migrant children is not exclusive to the Biden period. This issue has existed for years at the U.S.-Mexico border and has been observed under both Democratic and Republican administrations. For this reason, the thesis that all blame lies with Biden is also regarded as an element of political struggle.
Although Markueyn Mallin stated in his remarks that 146,000 children have been found, he did not provide extensive statistics regarding the conditions in which these children were discovered or how many people have been arrested on charges of human trafficking, sexual abuse, or fraudulent guardianship.
The U.S. Department of Justice announced that on the same day, charges were filed against several people related to some fake sponsorship schemes. However, these numbers appear quite small compared to the scope of allegations concerning hundreds of thousands of children. For this reason, a question is being raised in the U.S. media and on social networks: if the problem is truly this large, why have the broad criminal networks involved in the exploitation of these children not yet been fully exposed?
During discussions on the topic, many American observers often recall the case of sex offender Jeffrey Epstein. Although numerous facts about the sexual abuse of minors were revealed during the "Epstein case," part of society believes that not all connections and possible participants were fully investigated. Therefore, some political commentators ask the same question regarding the issue of 450,000 children—they ask why, if a large criminal network exists, its main organizers have not been presented to the public. However, currently, this parallel topic mostly carries political and public discussion character. Official bodies have not presented a legal connection between the two issues.
The topic is expected to hold a special place in the U.S. political agenda in 2026. The Trump administration presents the issue of "missing migrant children" as evidence of the failure of Biden’s border policy.
Markueyn Mallin’s harsh statements are precisely a continuation of this line.
The opposing side states that the problem has accumulated over decades and cannot be attributed to a single administration alone.
The U.S. government has faced serious problems tracking the subsequent fate of thousands of unaccompanied migrant children. Federal audits have also confirmed significant gaps in this area.
However, how many of the 146,000 children said to be found have been victims of exploitation? How many people have been arrested in these cases? What is the scale of human trafficking networks? Do the roots of the problem trace only to the Biden period, or are they older?
These questions remain open, and without clear answers, the claim of "450,000 missing children" will remain one of the most contentious topics in U.S. legal and political struggles. /Musavat.com
