(Reuters) - The internal watchdog for the U.S. Department of Homeland Security (DHS) has urged officials to take immediate steps to alleviate "dangerous overcrowding" after it found some adult detainees being held in "standing-room-only conditions" for days or weeks at a border patrol facility in Texas.
U.S. officials say they have been overwhelmed by tens of thousands of mostly Central Americans crossing into the United States and turning themselves over to border agents. President Donald Trump has threatened Mexico with tariffs to do more to stop the flow.
