And we need a president who is a uniter, not a divider; who can lower the temperature, not raise the temperature. And I wish President Trump would spend more time trying to go beyond his immediate base to reach people, and use the presidential microphone to try to bring people together, instead of the rhetoric that seems to divide us.

The Secret Service hates to complain about something. They're secret by nature. They're not boastful; they don't like to be in the limelight. And therefore, they need middle management, i.e., a Cabinet-level person, to be their advocate, to Congress, to the White House, to ensure that they have adequate funding.

I think that ISIS is a problem and it's really a symptom of a much greater problem.

With every case from years ago there should be lessons learned.

In my view, and in the view of a lot of intelligence experts, the terrorist threat that we face now has morphed significantly from the days of 9/11 to homegrown violent extremism. We have to be concerned and focused on homegrown violent extremism, countering violent extremism that exists within our borders.

The good news is that the international coalition, in which our military contributes, has done a lot to reduce the ground space, the territory in Iraq, Syria that ISIL once occupied a couple years ago. That's a good thing. And a lot of that, frankly, has occurred in Trump administration, so I'll give them credit for that.
