President-elect Donald Trump is at it again. Shortly after the news that Abdul Razak Ali Artan—who stabbed students on the Ohio State University campus Monday—was a refugee from Somali, Trump took to Twitter to claim he "should not have been in our country."
The attack left 11 people injured and Artan dead, CBS News reports. Artan was a permanent legal resident who came to the U.S. in 2014. He was also a student at OSU.
The terrorist group ISIS, also known as the Islamic State, has praised Artan's attack, according to a self-described news agency for the group.
Members of ISIS have reportedly called Artan a "soldier of the Islamic State" who had "carried out the operation in response to calls to target citizens of international coalition countries," CBS News reports.
The news station notes that the "praise" issued by ISIS has been used to lay claim to other violent acts and their perpetrators, but investigators have found no link between Artan and the Islamic terrorist organization or al-Qaeda.
