When we miss with all the metadata collection we've had, the San Bernardino couple and the Tsarnaev brothers, what that suggests to me is that we are using the wrong algorithms to search through all this data.

Fiscal policy is not just, or even not even principally, the purview of the president.

We need to fix our legal immigration system.

There's a whole company called Palantir that does nothing but derive and create algorithms riches to search through big data. We're not using their capabilities. For heaven's sake, some of this is just ineptitude.

We also know that ISIS is recruiting who are not in those databases. So of course, we're going to miss them. And then we now learn that DHS says, "No, we can't check their social media."

When our most important issue is the debt that we're piling on our children and grandchildren, I think it's pretty helpful to have someone in the U.S. Senate who has actually managed billions of dollars and knows how to cut billions of dollars.

I think what's fascinating is how many people are playing in politics who maybe haven't played before.
