"He sounded really calm on the phone and he started saying that he did it for the Islamic State — he did it for ISIS, and then he started speaking in a foreign language which at the time, being in Orlando, I thought it was maybe Spanish. But he was speaking so fast I didn’t know what it was, and thinking back now it was most likely Arabic, that he was speaking. I said ‘Sir, sir can you please speak in English?’ and then he started saying ‘I did it for ISIS, I did it for the Islamic State’ again. I didn’t know what to say to him. I was just blown away, and I asked him ‘Who is this? Where are you?’ and he told me that’s none of my effing business. He wouldn’t tell me who he was, he wouldn’t tell me where he was, but he wanted me to know that he did this for ISIS, he did this shooting for the Islamic State.”
See? He didn't do it for ISIL.
