I think Hillary Clinton is right. I think it isn't enough to leave [Bashir] Assad in place, because as long as he is there, there is going to be a recruiting magnet for ISIS.

I think Barack Obama has the overall right strategy and he's been right to resist bringing in massive numbers of American troops. The Iraqis would love to have Americans die for Iraq and the Syrians would love to have Americans die for Syria.

We should be worried about protecting the homeland. I think that policy is changing, should change and will change.

It was an echo of Director Comey's testimony that Trump showed no curiosity, no interest, no concern over the Russia hack. The only element of it that concerned him was how it might impact him personally. That says, I think, a lot about where the president is coming from, but it was quite jarring given this was an attack on our democracy by a foreign power.

I think what we are confronting now is a new war of ideas. It's not communism versus capitalism, but it is authoritarianism versus democracy and representative government. And that is a threat that here in Europe, they feel acutely. They've seen their countries interfered with, bombarded by cyber-attacks, by Russian propaganda, indeed, by Russian troops.

There are many reasons why the Russians prefer Donald Trump.I think, in the first instance, they wanted to tear down Secretary Clinton. They, I think, despised her remarks about the flawed 2011 elections in Russia. They feared that she would be very tough on Russia in terms of sanctions.

There was certainly merit to the criticism that the deputy attorney general Rod Rosenstein had about how James Comey handled the Hillary Clinton investigation. And I don't think Director Comey ever adequately explained why he treated the Clinton investigation one way and the Trump investigation another.
