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.

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.

There is no equivalency between the United States of America, the greatest freedom loving nation in the history of the world, and the murderous thugs that are in [Vladimir] Putin's defense of his cronyism. There's no moral equivalency there.

We should vigorously debate policy differences. We have too much all-or-nothing in American politics.

I don't understand what the president's [Donald Trump] position is on Russia. But I can tell you what my position is on Russia: Russia is a great danger to a lot of its neighbors, and [Vladimir] Putin has as one of his core objectives fracturing NATO, which is one of the greatest military alliances in the history of the world.

But fundamentally, health entitlements are the thing that will bankrupt our kids. We need to fix that for the long-term.
