I don't think he went off script at all, though (
except that hilarious part with the ICE guy LOL LOL LOL), but instead he's just a talking head expounding the beliefs of a bunch of white-power nationalist assholes, and Trump's afraid of "upsetting his base" of, like, not all that many people, really.
and this MS13 gang shit. Like, we have a bigger chance of being hit by lightening than being killed by a MS13 gang member. There ain't any here in Chicago. But the Trump team makes it like these MS13 guys are the majority of "Dreamers," infiltrating American society.
