at a rally, acknowledged that it was a controversial term. he said, we're not supposed to use that word. but he ultimately said he was talking about two things, trade and the fact that the u.s. spends a lot of money defending other countries and they don't chip in. >> right. and he says he's never heard the term "white nationalist" before, which is hard to believe, because it has been at the center of such discussion. >> i'm sorry, i think he clarified and said he meant he hadn't heard the conspiracy theory. that's what he meant. it was tough to hear with back and forth because the reporters weren't mic'ed. >> it is interesting in and of itself to see the president labelling himself as a nationalist. he's come close before, mentioned it. i actually believe earlier this spring at the white house but not in the declarative way he did last night. there is a reason presidents typically do not use that word because it has a negative connotation of extremism. that's why people say they're patriots. patriotism is loving your country for what it does,
