I think science is real.
Sometimes there's not a direct transfer of skills from business to government, but sometimes what happened in business would be really bad for government.
[Donald Trump] has a long record of engaging in racist behavior.
You know, Barack Obama is a man of great dignity. And I could tell how much it bothered him and annoyed him that this [birther lie] was being touted and used against him.
I like to remember what Michelle Obama said in her amazing speech at our Democratic National Convention: When they go low, we go high. And Barack Obama went high, despite Donald Trump's best efforts to bring him down.
Increasingly, we are seeing cyber attacks coming from states, organs of states. The most recent and troubling of these has been Russia.
We need to make it very clear - whether it's Russia, China, Iran or anybody else - the United States has much greater capacity. And we are not going to sit idly by and permit state actors to go after our information, our private-sector information or our public-sector information.
We're going to have to make it clear that we don't want to use the kinds of tools that we have. We don't want to engage in a different kind of warfare. But we will defend the citizens of this country.
The Russians need to understand. I think they've been treating it as almost a probing, how far would we go, how much would we do.
It's one of the reasons [Vladimir Putin invitation to U.S] why 50 national security officials who served in Republican information - in administrations have said that Donald [Trump] is unfit to be the commander- in-chief. It's comments like that that really worry people who understand the threats that we face.
I think there are a number of issues that we should be addressing. I have put forth a plan to defeat ISIS.
We also have to intensify our air strikes against ISIS and eventually support our Arab and Kurdish partners to be able to actually take out ISIS in Raqqa, end their claim of being a Caliphate.
I would also do everything possible to take out their leadership.
I think we need to go after Baghdadi, as well, make that one of our organizing principles. Because we've got to defeat ISIS, and we've got to do everything we can to disrupt their propaganda efforts online.
I hope the fact-checkers are turning up the volume and really working hard. Donald [Trump] supported the invasion of Iraq.
The only way that American troops could have stayed in Iraq is to get an agreement from the then-Iraqi government that would have protected our troops, and the Iraqi government would not give that.
How do we prevent attacks? How do we protect our people?I think we've got to have an intelligence surge, where we are looking for every scrap of information.
We've got to do everything we can to vacuum up intelligence from Europe, from the Middle East. That means we've got to work more closely with our allies, and that's something that Donald [Trump] has been very dismissive of.
We're working with NATO, the longest military alliance in the history of the world, to really turn our attention to terrorism.
We're working with our friends in the Middle East, many of which, as you know, are Muslim majority nations.
They [American Muslim community] need to have close working cooperation with law enforcement in these communities, not be alienated and pushed away as some of Donald's [Trump] rhetoric, unfortunately, has led to.
You know, NATO as a military alliance has something called Article 5, and basically it says this: An attack on one is an attack on all. And you know the only time it's ever been invoked? After 9/11, when the 28 nations of NATO said that they would go to Afghanistan with us to fight terrorism, something that they still are doing by our side.
[Donald Trump] even said, well, you know, if there were nuclear war in East Asia, well, you know, that's fine have a good time, folks.
I want to reassure our allies in Japan and South Korea and elsewhere that we have mutual defense treaties and we will honor them.
I would want to see the Supreme Court reverse Citizens United and get dark, unaccountable money out of our politics.
