We need Trump to lead the liberal democratic order around the world. No other nation can do that the way we can, and it's going to be very hard for Congress to do it over his opposition.

We still have a problem here in this country of access to airports and airplanes [for terrorists].

The war in Iraq has been extremely divisive here at home, and has also divided the world community.

I would need to see changes in the Iraq governance. Otherwise I don't think strikes are going to have any impact and could be very well counterproductive.

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.

All of the dirty tricks, basically, the Russians employ to tear down liberal democracy, we need to work together on a bipartisan basis, and we need the president Trump help. We can't do it alone. And that has to begin by his acknowledgment of the facts.

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.
