President Donald Trump's reversal of a policy separating migrant families at the Mexico border sparked confusion over how the new guidelines will play out.
There is concern that the changes don't go far enough, allowing children to still be held in detention, even if they remain with their families.
Trump said Wednesday he didn't like seeing children being removed from their families. But he also said his administration's "zero tolerance" on illegal immigration will continue, and children will be held with their parents while the adults are prosecuted.
It remains unclear what will happen with the more than 2,300 children separated from their parents at the border in recent weeks. Officials have said they are working to reunite families but have provided no clear answers on how.
