U.S. saw record number of unaccompanied migrant children enter shelters in 2021
New statistics from the Department of Health and Human Services show a historic 122,000 migrant children entered U.S. custody without their parents in 2021. The all-time high shatters a previous record set in 2019, with 69,000 minors. CBS News immigration reporter Camilo Montoya-Galvez joins CBSN to explain the reasons behind the increase.
