Question for President Joe Bidenâs Office of Refugee Resettlement, the federal agency charged with housing migrant minors: âWhere is your list of parents and relative sponsors to whom the children can be turned over rather than keeping them in cages that look a lot like the ones used by former President Barack Obama for weeks and even months on end?â Parents in the countries who allow their kids to travel unaccompanied to the U.S. border, and the relatives already in the U.S. expected to sponsor them on arrival, must know that theyâve arrived, so how about it?
