Thursday, April 22, 2021: Biden Makes A Climate Commitment

President Biden launches a climate change virtual summit with dozens of world leaders and makes a new pledge: cutting carbon emissions in the U.S. by as much as 52% by 2030.  Plus, the CDC director says the hard work now begins in convincing those still hesitant to get the covid-19 vaccine. And Colorado passed a police reform bill last year, including some limits on police officers' qualified immunity in civil cases. Could it serve as a model for legislation being negotiated now in Congress? On today's program: CNN's Kaitlan Collins, Manu Raju, Miguel Marquez, and Ryan Nobles. Also on the show: Earth scientist Rob Jackson, POLITICO's Laura Barrón-López, epidemiologist Caitlin Rivers and Colorado Attorney General Phil Weiser.
