WASHINGTON (AP) — The Biden administration is facing growing questions about why it wasn't more prepared for an influx of migrants at the U.S.-Mexico border.

The administration is scrambling to build up capacity to care for 14,000 young undocumented migrants now in federal custody, and more are likely on the way.

Immigration experts say the predicament was predictable.

Biden administration officials blame the Trump administration for making a mess of the immigration system.

Border patrol officials have encountered more than 29,000 unaccompanied minors since Oct. 1, nearly the same number of youths taken into custody for all of the previous budget year.
