I think that the holidays feel like frozen noses. I love walking with the dog for long periods of time.

Hopefully it's snowing and you've got to wrap up warm. So I think a frozen nose is a sweaty armpit

because your wrapped up so warm but then you're climbing hamps and heath and you get to the top

and you're like, and then you can see the breath but then your nose is still freezing to touch.

Welcome everybody to an Intelligent Squared program that we are calling Unresolved Information Disorder

because as we all know we are living in a time that is uniquely exposed to the perils of disinformation

which certainly makes it timely to hold a debate asking what should be done about it

and because at times disinformation is a national security threat we are delighted to be holding this debate in partnership

with the Homeland Security Expert Group, a whole audience of experts that is really something

and of course we have the experts on our stage. In this debate we are going to be working through three questions

one at a time and what we would like to do now is to ask you your opinion on these questions.

The three questions we are going to be looking at are should tech companies moderate misinformation that their users post

does American need a governing body to regulate this information and finally was Twitter right to ban Donald Trump?

I want to say now let's welcome our debaters to the stage.

First, former United States Secretary of Homeland Security and co-author of the Patriot Act, Michael Chertoff.

Next, internationally recognized expert on disinformation and democratization and author of How to Lose the Information War, Nina Jankowitz.

Now please welcome Principal at Cornerstone Government Affairs, Visiting Fellow at the National Security Institute,

former staff member on House Committee of Homeland Security and Georgetown University Professor Charles Carothers.

And finally former Assistant Secretary for Policy at the U.S. Department of Homeland Security under President George W. Bush, Stuart Baker.

So let's get to the debate. We're going to go through three questions and our first of three questions is this.

Should tech companies moderate misinformation that their users post? Let's see where each of you is going to argue on this.
