On this week's episode of 'The Sunday Show with Jonathan Capehart': Iowa! Iowa! Iowa! We are in the final countdown to the Iowa caucuses and with a new poll giving the last snapshot of the race before caucusgoers make their decision on January 15th, we'll go live to the Hawkeye state as the candidates compete with severe weather to make their closing arguments. Political strategist Rachel Bitecofer, The Nation correspondent Joan Walsh and Futuro Media founder and president Maria Hinojosa break down which candidates could be moving forward, who could be going home and whether the frigid weather will make or break their candidacy. Congressional leaders reach a deal to avert a government shutdown, at least until March. But some hard-right Republicans are poised to stand in the way.  House Minority Whip Katherine Clark joins me live to tell us what's going on. And on this Martin Luther King Jr. holiday weekend, my emotional conversation with the former speech writer and attorney for Dr. King. What Dr. Clarence Jones misses the most about the civil rights legend and his dear friend. All that and more on “The Sunday Show with Jonathan Capehart.”
