President Donald Trump announced the death of ISIS leader and founder Abu Bakr al-Baghdadi on Sunday morning, referring to Mueller by name, calling her a "beautiful young woman" who died while trying to "help people."
"We just learned that the whole thing is about Kyle thanks to General [Mark] Millie and it's very moving," her father Carl Mueller told ABC News on Sunday. "President Trump mentioned her today in his speech, and he mentioned that he deserves what he got for what he did to Kyle … she's not forgotten, and that's important."

Sitting next to his wife Marsha Mueller in an emotional interview at their Arizona home, Carl Mueller also revealed that the couple once traveled to Irbil for a face-to-face meeting. Umm Sayyaf, wife of ISIS oil Abu Sayyaf. The Delta Force killed Abu Sayyaf in May 2015 and captured Umm Sayyaf, who had previously held prisoner Kayla Mueller at their home for al-Baghdadi for sexual assault.
Carl Mueller said they went "against the FBI's advice" in the summer to find out what might have happened to their daughter's remains – or whether she might still be alive.
"When we spoke with Um Sayyaf, we found that we had more information from her, not just from us, the people who supported us – they received information from her that neither the Kurds nor the US government had received in two days, that we are there, "Karl Mueller said." There is a big difference when you talk to these people with a humanitarian attitude. We're not interested in what you did, what you did – we just want to know what you know about our daughter so we can bring her home. "
Through a meeting with Sayaf and others who had contact with Kayla Müller, they said they learned she was being held in solitude, tortured and raped by Al Baghdadi.
"We learned from women who were ransomed by their governments that she said she was kept in very cold, dark places, raped by al-Baghdadi, we know this is a fact, "said Karl Müller." She was killed by him or by someone in his organization. That is what we are striving for and we hope that President Trump will help us. "
The couple stated that they filed claims under the Freedom of Information Act to gather more information about how she might have died. The requests were denied and they were considering taking legal action to obtain documents related to her death.

In his public address on Sunday, Trump said that US special operations forces targeted al-Baghdadi in the Syrian attack on Saturday night. Eventually, the troops also turned him over to three young children whom he had taken captive.
Realizing that there was no way out, he blew a suicide bomb into a tunnel in a dead end, killing himself and his three children.
"He was a sick and debauched man. And now he is gone. Baghdadi was vicious and violent. And he died in a vicious and violent way, like a coward, running and crying," Trump said Sunday.
He also notes that al-Baghdadi committed the "particularly heinous" killings of innocent Americans in addition to Kyle Mueller, including freelance journalists James Foley and Stephen Sotloff and humanitarian worker Peter Casig.
"Think about the things he did to Kyle. … What he did to her was incredible," Trump said Sunday. "He held her captive for a long time; he held her captive, his personal captivity. She was a beautiful woman, a beautiful young woman, helping people. She was there to help people."
"And he saw her and he thought she was beautiful, and he took her captive for a long time and then killed her.
