Health and Human Services Secretary Alex Azar said the government will meet court deadlines to reunite migrant children who were separated from their parents by immigration authorities.
But reunited families may well remain in the custody of immigration authorities.

Azar told reporters on Thursday that officials have identified "under 3,000" children potentially separated from parents.
Of those, about 100 are under 5 years old. A federal judge in California has ordered the youngest children reunited by Tuesday and the rest before the end of this month.
Azar said DNA testing is being used to speed up matching parents and children.
