Standing up to ISIS

ABC News reorts about a courageous young woman from Arizona who stood up to ISIS while in captivity.

American hostage Kayla Mueller was tortured, verbally abused, forced into slave labor for ISIS commanders in Syria and raped by the group's top leader, but her fellow hostages say she never surrendered hope, she selflessly put the welfare of fellow captives above her own and she even stood up to executioner "Jihadi John" to defend her Christian faith.

Four former hostages who shared cells with Mueller, speaking publicly for the first time about their shared ordeal for ABC News' "20/20" broadcast, "The Girl Left Behind," airing Friday, say the Prescott, Arizona, humanitarian aid worker was a courageous 25-year-old who inspired them.

Update: Kayla's father has something to say to President Obama:

As President Barack Obama tried to console the parents of Kayla Mueller after she was killed in ISIS captivity last year, they say he offered to make a contribution to a foundation they had established in her name.

But he has yet to do so, the parents say, 17 months after he made his promise to them on March 13, 2015.

“I’m still waiting for that donation, Mr. President,” Carl Mueller said in an ABC News interview broadcast this morning on Good Morning America, as part of an hour long investigation to be aired tonight on 20/20.
