progressive tax system. that's why i've supported a capital gains tax in my state. i don't know where the right number is, but i would suggest that when dwight eisenhower is president, we had a lot higher emergen marginal tax rate. >> he was a republican and it was a 90% marginal tax rate. >> do you support a 70% or higher marginal tax rate on the 10 millionth dollar and above? >> i support increasing the progressivity of our tax code. what the right number is, i haven't identified a number, but i've identified a fact. and that is we need to address this massive income inequality. and our tax code that's gone backwards by giving more to the rich under donald trump has got to be reversed. and when we have a democratic nominee, i believe we'll do that. >> on 2020, as you know, your fellow washingtonion howard schultz is seriously considering an independent bid for the presidency in 2020. how do you feel about that?
