The WHO now saying what?</s>JACQUELINE HOWARD, CNN HEALTH REPORTER: The WHO has now declared that this outbreak is a pandemic. And this is a major, major announcement. It's a decision that the World Health Organization has not made lightly. And the fact that they are calling this a pandemic really shows that this outbreak has hit all continents, except for Antarctica. It's spread across so many countries. The World Health Organization Director General Tedros said that this outbreak has hit a number of countries that has tripled recently. So, the number of countries that have been hit by this outbreak has tripled. And again, a pandemic declaration is pretty serious. This is a major moment, John.</s>KING: A major moment, and we'll watch now to see how it intensifies the world's response. Jacqueline, really appreciate you coming here with that breaking news right there. When we come back, Bernie Sanders has a decision to make because Joe Biden is building a remarkable coalition.
