"Just confirmed that the replacement of Abu Bakr al-Baghdadi's number 1 was terminated by US troops. Most likely he would have taken first place – now he's dead too!" Trump tweets.
An American official told CNN that "the president is referring to ISIS spokesman Abu Hassan al-Muhajir."
A senior State Department official told reporters on Monday that Al Muhajir was killed by US forces in Aleppo province near Jarablus. "He was killed very close to the northeast, very close to the Euphrates River, near Jarablus," said an official. "He was killed by US forces."
The official introduced al-Muhajir as spokesman and "number two kind" of Baghdad.
Mazlum Abdi, commander-in-chief of the Syrian Democratic Forces (SDF), also said on Monday that al-Muhajir was killed in a coordinated operation between US military and SDF scouts near Jarablus in northern Syria.
The White House and the National Security Council did not say whether it was true that "US troops" were responsible for the death. The Pentagon said it had nothing to provide beyond the president's tweet.

In Jihadi circles he is known as Abdala Kardash, but the US Government designates him as Amir Mohammed Said Abdal-Rahman Al- Maula is believed to have known Baghdadi for at least 15 years.

Later that month, the United States added al-Moula to its list of justice awards, offering up to $ 5 million in information leading to its capture and saying that "as one of ISIS's oldest ideologues … he is a potential successor to ISIS leader Abu Bakr al-Baghdadi. "
