To prevent a crippling attack on our nation's critical networks, U.S. companies and the federal government must work together to combat those who wish to do us harm.

Without - you know, good intelligence stops plots against the homeland. Without that intelligence, we cannot effectively stop it.

Anything I can do to help destroy ISIS, I will support that.

There's no national strategy to deal with combating terrorism and foreign fighters.

What you're seeing is tension that we've seen for years between President Erdogan and his military, his military being more secular, President Erdogan being a little more in the Islamist side of the house.

My number one objective continues to be to defund or delay the implementation of Obamacare. But as long as any piece of this law is standing, it needs to apply to all Americans equally, and that includes members of Congress and our staff.

I think a lot of programs, policies have been put in place since 9/11, have prevented a 9/11-style attack. On the other hand, I think the threat has become greater, not lesser.

That's what really concerns me about the modern-day terrorists that we face is this global expansion.

This is an unprecedented pace of terror in modern times. And so, to say they're on the run absolutely defies reality.

We know there are terrorists communicating with individuals in the United States. We just can't see what they're saying.

Social media campaigns and the savviness of ISIS and propaganda is what greatly concerns us Homeland Security officials.

Currently, the United States provides 22 percent of the U.N. annual budgets, over $900 million in fiscal year 2007, and some of that funding goes to the Human Rights Council.

Violent extremism is going viral, but our response to it is moving at bureaucratic, sluggish speed.

We have a failed state in Syria.

The President of Iran has called for the destruction of Israel and the West and has even denied the holocaust took place. Iran and its terrorist arm Hezbollah are responsible for the current conflicts between Israel and Lebanon.

I think there's kind of a simplistic, kind of knee-jerk response that all you have to do is build a 2,000-mile wall, and problem solved.

In Europe, you have very different situation than you do in the United States. In Europe, it's very segregated. And you have the diasporas in Belgium that I saw. And they're being radicalized because they're not assimilated with the culture. I don't think we have that same situation in the United States.

Now we're dealing with a younger generation of terrorists that are very, very savvy with computer skills, very savvy over the Internet, and very savvy with social media of the likes that we have never seen before.

On this National Agriculture Day, when we all should be taking time to thank and pay tribute to America's farmers, ranchers and their families who produce the food for our tables, we are finding those same people in dire need of our help and support.

We are ramping up security in the United States but also looking at visa applicants, visa waiver applicants - and looking at travel manifests on the airplanes trying to come into the United States.

We think there should be a better countering-violent-extremism effort, that there should be a lead agency tasked to handle that.

I take ISIS at its word. When they said, in their words, 'We'll use and exploit the refugee crisis to infiltrate the West,' that concerns me.

200,000 ISIS tweets a day, 1,000 investigations in all 50 states. It's really hard to stop all of it. But we have to get control over this Internet propaganda that is poisoning the minds of the United States.

We're trying to find needles in the haystack, and the needles are going dark, and it's because of this phenomenon we can't track their movements.
