The Trump administration has repeatedly denied that its policy is to separate children from their parents when families cross the US border illegally.
But its own internal documents contradict that.
The Department of Homeland Security's website put out a press release on Friday saying it would separate children from their families.
A "zero tolerance" policy from Attorney General Jeff Sessions mandates that anyone illegally crossing the border be treated like a criminal.

The Trump administration has repeatedly sought to distance itself from its policy separating children from their parents when families cross the US border illegally, but its own internal documents contradict those efforts.

President Donald Trump had previously tried to blame the policy on Democrats, but over the weekend his secretary of homeland security, Kirstjen Nielsen, flat-out denied that such a policy existed.

"We do not have a policy of separating families at the border. Period," Nielsen tweeted.

But the Department of Homeland Security does separate children from their parents at the border, and it just put out a press release about it on Friday, explaining its new "zero tolerance" policy for border crossers.
