Trump ended separating families; now what's next?

MCALLEN, Texas - President Donald Trump has signed an executive order ending the administration's practice of separating immigrant families, but many issues concerning immigration remain up in the air. Among the key questions still pending: what happens to more than 2,300 children still in custody and away from their parents?

Here's a guide to key questions on immigration.

Question: Does President Trump's executive order mean all immigrant families who arrive at the border will no longer be separated?

Answer: Not entirely. While the order said that it is "the policy of this administration to maintain family unity" it also said the Trump administration plans to do so "by detaining alien families together where appropriate and consistent with law and available resources."

The order also directed the Homeland Security secretary to house families together "to the extent permitted by law and subject to the availability of appropriations." That leaves the possibility that immigration officials could still separate families due to space constraints at Border Patrol processing centers where they are initially held, and Immigration and Customs Enforcement family detention centers where they stay longer term.

Border Patrol officials have long reserved the right to separate families when they fear adults could pose a danger
