Once we affirm the goal of trying to make sure that you don't have jihadis infiltrating terrorist flows, we need to make sure we're doing it in a thoughtful way that's thinking about the 10 and 15 and 20 years long battle we're going to have against jihadists.

People think if they voted for somebody, they should reflexively defend everything they do or say. And if you voted against somebody, you should just as reflexively oppose everything they do or say. It's not very helpful. What's more constructive for our kids is to go on a case-by-case basis, evaluating particular policies.

We're not at war with all Muslims, we're at war with a subset of Islam that believes in killing in the name of religion, as jihadis do.

The president is the president. And every American, regardless of who you voted for, if you voted for Donald Trump, Hillary Clinton, Donald Duck, I don't really care. We should all hope that the president does a good job, that he's surrounded by wise counselors, that he advances U.S. interests.

While Admiral Neffenger is an impressive man, it is naive and dangerous to pretend installing one director can heal what ails TSA, the Department of Homeland Security needs to admit that it has a crisis of bureaucratic complacency - lacking an overarching vision and coherent measures of success and failure.

Let's be clear: Has the U.S. ever made any mistakes? Of course.Is the U.S. at all like [Vladimir] Putin's regime? Not at all.

So [Vladimir] Putin is a mess. He's committed all sort of murderous thuggery, and I am opposed to the way Putin conducts himself in world affairs, and I hope that the president also wants to show moral leadership about this issue.
