Lawmakers condemn "horrific" conditions faced by asylum-seekers returned to Mexico

One-by-one, members of a congressional delegation described the squalid conditions faced by the asylum-seeking families and children they met in Matamoros, Mexico, where the U.S. has returned thousands of migrants, requiring them to wait for their U.S. immigration court hearings on the Mexican side of the border.

Other members of the delegation echoed Castro's remarks. Recalling an encounter with a mother from El Salvador with a sick child, Oregon Congresswoman Suzanne Bonamici called what she saw in Mexico "heart-breaking."
