Talking to The Arizona Republic on Sunday, Oct. 27, parents of ISIS hostage, Kayla Mueller claimed that their daughter might still be alive if President Obama had been as “decisive” as President Trump in dealing with ISIS.

Mueller was a U.S. human rights worker who died in 2015 after two years in ISIS custody. She was reportedly abducted by ISIS after entering Syria to visit a hospital.

According to her father, Carl Mueller, she was subject to confinement, torture, and repeated sexual abuse by Baghdadi himself. ISIS claimed she died in a Jordanian airstrike in Raqqa at the age of 26.

Since then, her parents have been longing for more information about her death. They said they were asked to keep silent about their daughter’s detention by U.S. authorities back then. But Marsha Mueller stressed that they still want to know where Kayla Mueller is and she is praying with all her heart that someone in this world will bring them those answers.

They now hold more hope that the Trump administration would be more helpful to them, saying “For me what matters most I’m hoping now we will finally get the answers we have been asking for all along,” Marsha Mueller added. “I think this administration truly might help us. I don’t think they are as closed about what happened.”

Carl Mueller felt grateful that President Trump knows about their story, stating, “He knows her story. He’s been briefed on it, and he knows, and that’s important to me,” Carl Mueller said. “I don’t think anything would have stopped him from getting this guy.”

On Sunday’s speech on the death of ISIS leader Abu Bakr al-Baghdadi, President Trump mentioned Kayla’s story saying, “He kept her in captivity for a long period of time. He kept her in his captivity, his personal captivity. She was a beautiful woman, beautiful young woman. Helped people. She was there to help people. And he saw her, and he thought she was beautiful, and he brought her into captivity for a long period of time, and then he killed her. He was an animal, and he was a gutless animal.”

National Security Adviser, Robert O’Brien told NBC’s “Meet the Press” on Sunday that the U.S. operation taking down al-Baghdadi was named after Mueller.
