A raid carried out by U.S. troops in Syria against ISIS was named after Prescott-native Kayla Mueller. The raid was announced by President Trump Sunday morning. Troops had ISIS leader Abu Bakr al-Baghdadi cornered when he triggered a suicide vest Saturday that killed himself and three children. Ambassador Robert O’Brien, who is currently the White House National Security Advisor, appeared on NBC’s “Meet The Press” Sunday and said the operation was named after Mueller, who was captured in August of 2013 as she was working at a Syrian hospital for the humanitarian group, Doctors Without Borders. The 26-year-old attended Tri-City College Prep in Prescott and was a 2009 graduate of NAU, where she received a degree in political science. Mueller was being held for 18 months before she was killed in a Jordanian air strike in 2015.
