clean, renewable energy future. i have put forth plans, paid family leave, tuition, debt-free tuition for public colleges, tapping prescription drug costs and much more. and it would cost about $100 billion a year, all of which i pay for. in contrast, senator sanders has very big ideas but he hasn't yet told anybody how he would pay for them. he had promised that he would roll out his tax plans before the iowa caucus on february 1st. well, if you wait too long nobody will have a chance to see them or analyze them and so, i am very clear about what i would do and how i would pay for it. >> another point of conflict between you and senator sanders is on gun policy. >> uh-huh. >> we watched this very emotional event that you were involved in where this mom whgç lost two children to gun violence got up and spoke. >> right. >> it was heartbreaking to hear her. it sounds like she lost her children to criminals.
