BERMAN: All right. We're getting our first look at these pictures coming in from Venezuela, this is Caracas. Just huge, huge protests there. This comes after years of a collapsed economy, food, medicine shortage. The president there, Nicolas Maduro, called for the army to patrol the streets during these protests and also for his own supporters to stage a counter march.</s>HARLOW: Right. Stefano Pozzebon, a journalist, is live in Caracas for us. What are you seeing and what is the background to all of this?</s>STEFANO POZZEBON, FREELANCE JOURNALIST: Yes, Poppy. Thank you for having me. This is the main opposition march that we're seeing since the beginning of the year and the opposition here has tried of course as you've correctly said in the midst of an economic crisis that has completely collapsed the social texture of the country, has been trying to oust President Maduro for years, last year, through a recall referendum on his power. That move didn't go through because the Supreme Court blocked it and now they're trying to oust him by straight action by marching and trying to gather as much support as possible. So what you're seeing just behind me is one of the gathering places where opposition protesters are gathering together to try and march towards the presidential palace and towards the center of Caracas, but it is too early to see if the turnout will be good enough and if the momentum was reached towards the opposition and if Venezuela will try to enter a new cycle in the midst of the most dramatic economic crisis that this country has seen in recent history.</s>HARLOW: They're calling it the mother of all protests. Again you're looking at pictures out of Caracas. Thank you so much, Stefano Pozzebon. We'll bring you more as we have that. Also still to come for us, president -- former president George H.W. Bush is back in the hospital this morning. Why? How serious is it? Our Dr. Sanjay Gupta will join us next.
