CHRIS CILLIZZA, CNN POLITICS REPORTER & CNN EDITOR-AT- LARGE:  CILLIZZA: One person we know is running for president in 2020 is Elizabeth Warren. This week started, it feels always like a month ago, but this week started with Elizabeth Warren releasing that five- plus minute video on the DNA test and the Stanford geneticist saying --</s>KATE BOLDUAN, CNN ANCHOR: It sounded like a campaign video in itself.</s>CILLIZZA: Exactly. But it started with her trying to put that behind her, saying, look, I know Donald Trump is going to attack me, but I have a foolproof response. By the end of the week, not just Nikki Haley, we heard from plenty of people saying it didn't work as well as we or she had hoped. It's sort of a book end to the week that began with this surprise video from Elizabeth Warren.</s>BOLDUAN: If you learn anything from 2016, never apologize. Just double down, triple down, and keep whatever. Keep going.</s>CILLIZZA: That's right.</s>BOLDUAN: Great to see you, Chris.</s>CILLIZZA: Thank you, Kate. Thanks for joining me. All right, coming up for us, Beto O'Rourke goes where a lot of top Democrats says he should not go. Who's right? That's next.
