I introduced bill saying we need more security, we need more scrutiny. Once again, Marco [Rubio] opposed this. So Marco can't have it both ways. He thinks he wants to be this, "Oh, I'm great and strong on national defense." But he's the weakest of all the candidates on immigration. He is the one for an open border that is leaving us defenseless.

In fact, I think we're less safe. We get so distracted by all of the information, we're not spending enough time getting specific immigration - specific information on terrorists.

The problem we have is not Democrats versus Republicans. It is a Washington cartel. I've said many times the biggest divide we have politically is not between Republicans and Democrats. It's between career politicians in both parties and the American people.

You have to be willing to have the decision-making follow the data.

President Obama fuels that perception. That will change when militants across the globe see that when you join ISIS that you are giving up your life, you are signing your death warrant.

President Obama, when he was elected, he could have been a unifying figure. He could have chosen to be a leader on race relations and bring us together. And he hasn't done that, he's made decisions that I think have inflamed racial tensions that have divided us rather than bringing us together.

We are seeing Republicans uniting behind this [presidential] campaign [2016].
