The family of Kayla Mueller, a humanitarian aid worker who was kidnapped, tortured, raped, and ultimately killed by ISIS from 2013 until 2015, praised the U.S. military and the Trump administration for the death of ISIS leader Abu Bakr al-Baghdadi, saying that they believe their daughter may have lived “if Obama had been as decisive as President Trump.”

"We are so grateful for them ... we are so grateful," Marsha Mueller said, the Arizona Republic reported.

"I still say Kayla should be here, and if Obama had been as decisive as President Trump, maybe she would have been," she added.

"For me, what matters most I'm hoping now we will finally get the answers we have been asking for all along. I think this administration truly might help us. I don’t think they are as closed about what happened."

President Trump on Sunday announced al-Baghdadi had been killed in a suicide blast during a U.S. Special Forces raid on his compound. Mueller, who was only 24 at the time she was kidnapped, had reportedly been held captive and violated by the ISIS leader himself during her time as an ISIS prisoner.

Speaking of Trump, Carl Mueller, Kayla's father, said he doesn't think the president would have stopped trying to get justice for his daughter.

"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."
