He vowed to "hold ICE accountable for this monstrous action."
A spokesperson for the U.S. Department of Homeland Security, Tricia McLaughlin, said Wednesday that the child was in "stable condition and medically cleared for removal" and that pediatricians gave the parents a nasal saline spray with a nasal bulb syringe to continue care.
McLaughlin said Border Patrol apprehended the child's mother, Mireya Stefani Lopez-Sanchez, crossing the border illegally near Eagle Pass, Texas, on Jan. 21.
Lopez-Sanchez chose to take her child with her when Border Patrol transferred her to ICE custody, McLaughlin said.
"All of her claims were heard by a judge and found not to be valid," McLaughlin said.
