On Monday, Abdul Razak Ali Artan — an 18-year-old Somali refugee, legal permanent resident of the United States, and Ohio State University student — plowed a car into a crowd of people on the school’s Columbus campus and then began stabbing them with a butcher knife, injuring 11.
Within one minute of the attack, a campus police officer shot and killed Artan, who, according to President-elect Donald Trump, should never have been in the country.
“ISIS is taking credit for the terrible stabbing attack at Ohio State University by a Somali refugee who should not have been in our country,” Trump tweeted Wednesday morning.
Since the attack, authorities have been looking into whether terror was a motive, pointing to a Facebook post Artan wrote shortly before his rampage. In it, he warned the United States to “make peace” with Muslims and referenced a late Al Qaeda leader in Yemen. On Tuesday, ISIS called Artan a “soldier” of the Islamic State.
