2020 Democratic candidates focused on attacking Sen. Elizabeth Warren at the fourth debate on her proposed health care plan. Joe Scarborough says: "It was striking how much they went after Elizabeth Warren... She is actually creating talking points that Republicans will use ... if she doesn't answer the question: 'how are you going to pay for a Medicare for All plan?'... She just can't answer that question."
