In a particularly galling detail of an already unbearable story, a story has come out about a 10-year-old girl with down syndrome who is among the 2,000+ children who have been separated from their parents at the US border in recent weeks.

Mexico's Foreign Minister, Luis Videgaray, has said that girl and her brother were sent to a detention center in McAllen, Texas, whilst their parents were sent to a separate facility over an hour away, CNN reports. This is despite a statement from the Mexican government that the father of the children is a legal US resident.

"It's a particularly painful case," Videgaray told a Mexico City news conference. "The Mexican government in no way promotes illegal migration. However, according to our constitutional principles and our convictions, we cannot be indifferent before an act that clearly represents a violation of human rights and that puts into a vulnerable position minors, children, including those with disabilities."

It's a damaging situation for all the children involved. Research suggests the stress can even shorten the life of children who go through separations like this.

You'd hope that anyone hearing the details of this story would be horrified. Not so, former campaign manager to Trump, Corey Lewandowski.

When Lewandowski was told on a Fox News segment that a "10-year-old girl with Down syndrome was taken from her mother and put in a cage," his response was to dismiss it by making "womp womp" noises.

"Did you just say 'womp womp' to a 10-year-old with down syndrome being taken from her mother? How dare you. How dare you?!" former Democratic National  Committee adviser Zac Petkanas, who had shared the story, responded angrily, whilst Lewandowski attempted to interrupt.

"We have infants that are being taken from their mothers. We have infants that have been stolen from their mothers and put into cages, and you go womp womp? She has down syndrome and she was taken from her mother."

There has been some confusion as to whether Lewandowski was mocking the child with Down syndrome or his liberal opponent for having a heart, but this rather clears it up.

Many Trump supporters are trying to pass the policy off as Obama's, even though this isn't true at all, and any accidental separations under the Obama administration were corrected as quickly as possible, "even if that meant release of a parent from adult detention," Denise Gilman, a law professor at the University of Texas School of Law told Politifact.

"There is a reason why the governor of New York is suing this administration to stop this policy," Petkanas said. "This policy is abhorrent. It is offensive to all moral people."

The reaction from people who have never been involved in a Trump campaign is, as you'd imagine, less than favorable.
