Abu Bakr al-Baghdadi

The Islamic State named Abu Ibrahim al-Hashimi al-Quraishi as its new leader days after ISIS founder Abu Bakr al-Baghdadi killed himself during a U.S. raid on his compound in northwest Syria.

The president said the U.S. had been searching for Abu Bakr al-Baghdadi for years. Capturing or killing Baghdadi has been "the top national security priority" of the administration, Trump said Sunday.
