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.

A White House official confirmed to ABC News that the president had not made the donation but still intends to do so.

The official offered no guidance on why the president had failed to make the donation.

“He asked what he could do for you,” recalled Marsha Mueller, Kayla’s mother, about a private meeting when the president travelled to Phoenix, Arizona, after their daughter’s death.

“He says, ‘You won’t know, it’ll be an anonymous donation but I will,’” recalled Kayla’s father.
