HARLOW: All right. Welcome back. The Democratic presidential field just got a little bit bigger. This morning, Washington governor Jay Inslee formally announced he's joining the race for 2020. And he is making climate change the central pillar of his campaign.</s>JAY INSLEE, WASHINGTON GOVERNOR: I'm Jay Inslee and I'm running for president because I'm the only candidate who will make defeating climate change our nation's number one priority. We can do this. Join our movement. This is our moment."</s>HARLOW: He is the first governor to officially jump in the race. And he's up against some serious Washington heft. A new poll from New Hampshire shows Senator Bernie Sanders and former Vice President Joe Biden -- who, by the way, hasn't even announced a run yet -- leading the field of declared and likely Democratic candidates. We'll see if that climate change pitch works for Inslee. We'll be watching it. Thank you all for being with me today. I'm Poppy Harlow. Jim will be back in the chair next to me on Monday morning. Have a great weekend. "AT THIS HOUR WITH KATE BOLDUAN" starts right now.</s>KATE BOLDUAN, CNN ANCHOR, AT THIS HOUR WITH KATE BOLDUAN: Hello everyone. I'm Kate Bolduan.
