US President Donald Trump has signed an executive order stopping his administration's contentious policy of separating children from their parents when they are detained for illegally crossing the US border this morning.
Here's what you need to know:
The dramatic dramatic turnaround from Trump, is believed to have been sparked by the concerns of his daughter and wife.
A White House official said first lady Melania Trump had been making her opinion known to the president for some time that she felt he needed to do all he could to help families stay together, whether by working with Congress or acting on his own.
And daughter Ivanka Trump tweeted, "Thank you (at)POTUS for taking critical action ending family separation at our border." after reports she asked her father to change his stance.
Searing images of children held in cages at border facilities have dominated the news in recent days, along with audio recordings of young children crying for their parents.
The images has sparked fury, questions of morality and concern from Republicans about a negative impact on November's midterm elections.
The order does not end the "zero-tolerance" policy that criminally prosecutes all adults caught crossing the border illegally.
However, it will keep families together while they are in custody, expedite their cases and ask the Department of Defense to help house them.
It's unclear when families will start being reunited with their families.
Health and Human Services Secretary Alex Azar said his department will start reuniting detained immigrant children with their parents - but he's making no specific commitment on how quickly that can be accomplished.
Assessments for possible detention facilities at military bases have already been done in Texas and another is expected in Arkansas on Thursday.
