Capt. Christopher Hulser outlines the US Coast Guard's rescue efforts in Louisiana following the devastation of Hurricane Ida. "We've actually got nine states' worth of Coast Guard forces here. We've got ships at sea that are moving in from the south. We've got 54 aircraft on the left and the right side of the storm ... Hoisting people off of rooftops if they need, from clearings, taking them to hospitals or just safer places to be," he tells CNN's John Avlon. https://cnn.it/3kuRM2c | CNN
