BILL O'REILLY (HOST): Why do you think President Obama is not fighting ISIS as aggressively as, perhaps, he could?
DONALD TRUMP: I think nobody knows, Bill. I have absolutely no idea. All I know is that he should be. Why he doesn't fight it and why he doesn't fight it with strength and with vigor, nobody knows. That's certainly a topic of conversation for plenty of people, but he is not doing a good job, that is for sure.
O'REILLY: Now, if you don't know, and I don't know either, although I think that he believes that his outreach to the Muslim world, that the president's personal outreach, he believes de-intensifies terrorism directed at the USA. I think he believes that. But you said this morning on Fox & Friends, or you implied there may be a sinister reason for him not engaging ISIS more aggressively. Do you want to define that further?
TRUMP: I can't define it, I mean nobody knows what's going on. Nobody knows why he doesn't have more anger, why he doesn't have more competitive zeal. He's a competitive person, why doesn't he have more competitive zeal to knock them out, Bill? I mean, look at what's going on, look at what's happening. This Orlando attack was just absolutely horrendous and, yet, he still doesn't even use the word of radical Islamic terror. I mean, he won't even issue the words.
