Transcript for Bernie Sanders Says No Second Thoughts on Hillary Email Comments

But I think the secretary is right. And that is that the American people are sick and tired of hearing about your damn e-mails. Thank you. Me too, me too! It was the moment of the debate on Tuesday and now Bernie sanders joins us live from Iowa this morning. Senator sanders thank you for joining us. You heard the applause after that moment. But a lot of people watching and said you'lled the deal for Hillary taking away her biggest vulnerability. Any second thoughts? I don't think so. I think what the American people want, George, is a discussion in this country of the real issues that are impacting them and that is they're asking why it is they're working longer hours for lower wages, why we have a massive level of warmth -- wealth such that all is going to the top 1%. They want a discussion, why they can't send their kids to college. Why we have today more people in jail than any other country on Earth. 2.2 billion people and why we're not investing in our young people in jobs and education rather than more jails and incarceration. Why we are not dealing with the reality of who controls our rigged economy and a corrupt political system as a result of citizens united is allowing billionaires to buy elections. The great global crisis facing our country. All of those issues are more important than Hillary Clinton's e-mail issues. Of which there is a process under way to determine what happened. Also questions about national security. President Obama announcing he's keeping 10,000 troops in Afghanistan through next year. 5,000 after that. You heard Ben Carson saying he supports that decision. So does Hillary Clinton. Do you? Well, yeah. I mean I won't give you the exact number. Clearly what the president has been trying to do and I say this as somebody who voted against the war in Iraq. A war which destabilized the entire region. Clearly we do not want to see the Taliban gain more power and we need a certain nucleus of American troops in Afghanistan to try to provide the training and support the Afghan army needs. You were asked about when you would authorize the use of force. You talked about previous vote authorizing the use of force and including in Afghanistan and went on to say I do not support the U.S. Getting involved in unilateral action. So there are no circumstances where president sanders would authorize unilateral action? I won't get into hypotheticals. This is what I will say. I will say bush's decision to get us into a war in Iraq unilaterally was one of the worst foreign policy blunders in the history of the united States. It destabilized the entire region and led us to where we are today. I think sensible foreign policy and military policies suggest it cannot be the United States of America alone which solves all the world's military -- In all circumstances? Of course, I'm not saying -- no, I don't want to get into hypotheticals. I didn't say in all circumstances. But I do believe, number one, and I think if there's a lesson to be learned from Iraq and Afghanistan that what a great military power like the united States is about is try to use diplomacy before war and working with other countries rather than doing it alone. At the end of the day coalition, military coalition is what will succeed not the United States doing it alone. Donald Trump took off on you on the stump this week. Let's take a look. He's going to tax you people at 90% and take everything. And nobody has heard the term communist. I call him a socialist/communist because that's what he is. You smiled. What's your response? If I had to respond to every absurd thing to what Donald Trump said I would spend my whole life doing it. I want to raise the issue of taxes. Trump raised that issue. Let's talk about it. What we have seen George in the last 30 years as most of Americans know is a massive redistribution of wealth. Unfortunately it's gone in the wrong direction from the middle class and working families to Donald Trump and his friends to the top .0001%. Yes, let me be very clear. If we're going to make public colleges and universities tuition-free as we have to do in the 21st century. Yeah we are going to have a tax on Wall Street speculation and ask trump and his billionaire friends to pay more taxes. At what rate? We'll come up with it. But higher than it is right now. When you see the rich getting much much richer and their effective tax rates as Warren Buffett often reminds us is lower than the effective tax rates of truck drivers and nurses, the wealthy have to pay more and corporations paying billions of dollars in taxes. Billions of dollars in profits. That has got to change. You said a -- previously you had been asked if the 09% rate is too high and you said no. How high are you willing to go on that rate? Are we talking 50%, 60%? This is what we're working on right now. We're going to end the loophole that allows large corporations to stash their money in the cayman islands and in some cases avoid paying all federal income taxes and raise the estate tax so that trump and his billionaire friends and their families will pay more in taxes and have tax on Wall Street speculation. Trillions of dollars have flowed from the middle class to the top .001% and we have to address the fact that the middle class is disappearing and they need help. We have massive wealth and income in quality. But you have to do more than tax the top 1%. How far below are you going to go with tax hikes? It is not true that we have to go much further. I indicated to you some proposals that we have. The proposals that we have to provide public colleges and universities tuition-free will be paid by a tax on Wall Street speculation. Rebuilding our crumbling infrastructure. A huge need out there and creating millions of decent jobs will be paid by doing away with the loophole that allows the corporations to stash their money in the cayman islands tax-free. We have huge amounts of tax loop holes. We're going to address that issue. And protect the working families and middle class. No tax hikes below the top 1%? I didn't say that. I think if you are looking about guaranteeing paid family and medical leave which every other major country has so that when a mom gives birth she doesn't have to go back to work in two weeks. Or an illness in a family, dad or mom can stay home with the kids. That will require a small increase in the payroll tax. Senator gilibrand's legislation. And we can accomplish that just with the small increase in the payroll. That's going to hit everybody. That would hit everybody. Yeah, it would but it would mean we were drawing the rest of the industrialized world and make sure that when a mom has a baby she can in fact stay home with that baby for three months rather than go back to work at the end of one week. We are the only country, only major country that doesn't guarantee paid family and medical leave. The truth of the matter is we do a lot of great things in this country but we are behind many other countries in protecting the middle class and working families. One area that I want to touch on the social security administration said there would not be a cooler for our seniors and disabled people. I think that's absurd. Prescription drug costs have gone up. Seniors are paying more. We need to change the formula. We have got legislation in to do that to ascertain what real cost of living is for seniors. I'm going to fight very hard. You have got millions of seniors getting by on $13,000, $14,000 a year. Making choice between medicine and food. That is criminal and we have got to change the formula so that seniors get a fair shake. I got to show you Larry David on Saturday night live. I'm the only candidate up here who is not a billionaire. I don't have a super pack, don't even have a backpack. I carry my stuff around loose in my arms. You know, between classes. He seems to have nailed it. What do you think? I think we'll use Larry on our next rally. He does better than I do. Okay, Bernie sanders, thanks very much for joining us this morning. Thank you.
