Succession: How Biden will unite America in a post-Trump world

While Democrats rejoice that they have taken back control of Congress and the White House, President Biden is already working toward eliminating the division the U.S. currently faces. Writer, journalist and executive producer of the hit show "Succession" Frank Rich joins MSNBC's Ari Melber to discuss Biden's first days in office and the road ahead of him as he works to rebuild America. Rich points out the GOP's hypocrisy on unity and warns "there is a terrorist white supremacist movement in this country" and that "it has members on the floor in Congress."
