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.

When Donald Trump focuses on a fight with the press or investigating leaks but doesn't seem committed to standing up to what Russia is doing at home and around the world, that is of profound concern.

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

I'm concerned the clock is ticking, and the danger to the American people is still very present.

But it is equally incontrovertible that if our intelligence gathering process is seriously flawed, we had better find out and find out fast if we are to avoid another Sept. 11.

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.

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.
