Joe Biden in Iowa Democratic Primary Debate

On Energy & Oil: I introduced the first climate change bill in 1986

Look, what we have to do is we have to act right away. And immediately, if I'm elected president, I'll reinstate all the mileage standards that existed in our administration which were taken down. That's 12 billion barrels of gasoline to be saved immediately.

And with regard to those folks who in fact are going to be victimized by what's already happened, we should be investing in infrastructure that raises roads, makes sure that every new highway built is a green highway, having 550,000 charging stations.

We can create millions of good-paying jobs. We're the only country in the world that's ever taken great crises and turned them into great opportunity.

On Health Care: 4% tax doesn't bring in trillions to cover Medicare for All

Sen. Bernie SANDERS: Medicare For All will cost substantially less than the status quo. Medicare For All will end the absurdity of paying the highest prices in the world for prescription drugs and health care, while we have 87 million uninsured and underinsured. Under Medicare For All, one of the provisions we have to pay for it is a 4% tax on income, exempting the first $29,000. So the average family in America that makes $60,000 would pay $1,200 a year, compared to that family paying $12,000 a year.

On Health Care: Add mental health parity to ObamaCare, with Biden option

On Principles & Values: Trump's lies about me are so bad that TV won't show them

BIDEN: It's irrelevant. There's no choice but to move [forward with impeachment. Trump] has, in fact, committed impeachable offenses. I understand how these guys are, this Republican Party. They've savaged my surviving son, gone after me, told lies that your networks and others won't even carry on television because they're flat-out lies. I've got to be in a position that I think of the American people. I can't hold a grudge.

Q: President Trump has no problem mocking people, using insulting nicknames, slinging mud and telling lies. Are you prepared for that?

BIDEN: I am prepared for that. Look, I've been the object of his affection now more than anybody else on this stage. I have to be able to not only fight, but also heal. And as president of the United States, that's what I will attempt to do.

On War & Peace: Pull troops out of Mideast, except to patrol Gulf and ISIS

Sen. Bernie SANDERS: What we need to do is have an international coalition. The nuclear deal with Iran was worked on with a number of our allies.

BIDEN: I was part of that deal to get the nuclear agreement with Iran. And it was working. It was being held tightly. There was no movement on the part of the Iranian government to get closer to a nuclear weapon.

Q: So would you leave troops in the Middle East or would you pull them out?

BIDEN: I would leave troops in the Middle East in terms of patrolling the Gulf, where we have--where we are now, small numbers of troops, and I think it's a mistake to pull out the small number of troops that are there now to deal with ISIS. And with regard to this idea that we can walk away and not have any troops anywhere, including special forces, there's no way you negotiate with terrorists.

On War & Peace: As veep, worked to end Iraq war

Sen. Bernie SANDERS: When Congress was debating whether or not we go into a war in Iraq, I said that would be a disaster. I helped pass a War Powers Act resolution, working with a conservative Republican, Mike Lee of Utah, which said that the war in Yemen, led by Saudi Arabia, was unconstitutional because Congress had not authorized it. We got a majority vote in the Senate. We got a majority vote in the House. Unfortunately, Bush vetoed that and that horrific war continues.

On War & Peace: Iraq war vote mistake based on Bush/Cheney lies

Sen. Bernie SANDERS: The war in Iraq turned out to be the worst foreign policy blunder in the modern history of this country. We lost 4,500 brave troops. Hundreds of thousands of Iraqis died. We have spent trillions of dollars on that endless war, money which should go into health care and education and infrastructure in this country. Joe and I listened to what Dick Cheney and George Bush & Rumsfeld had to say. I thought they were lying. I didn't believe them for a moment. Joe saw it differently.

On War & Peace: Leave special forces in Mideast, not just combat troops

Sen. Elizabeth WARREN: We need to get combat troops out of the Mideast. We have to stop this mindset that we can do everything with combat troops. Our military is the finest military on Earth and they will take any sacrifice we ask them to take. But we should stop asking our military to solve problems that cannot be solved militarily. Our keeping combat troops there is not helping. We need to work with our allies. We need to use our economic tools. We need to use diplomatic tools.
