Any country that makes U.S. service members get on their knees will feel the full force and fury of the United States of America.

I believe in a America first foreign policy, that far too often President [Barack] Obama and Hillary Clinton - and, unfortunately, more than a few Republicans - have gotten distracted from the central focus of keeping this country safe.

If we look at it more from a philosophical standpoint, these foundations of atheism and secular humanism believe that you are your own God. That leads us to something that unfortunately has crept into many churches across America, and it is what I call the Social Gospel. The social gospel, that could creep into something that is called Liberation Theology, which is a mixture of leftist, pseudo-Christianity with Marxism.

On his [Marco Rubio] Gang of Eight bill, he would have liberalized immigration, but he did not - and he steadfastly opposed any new border security requirements for refugees or students.

We need leaders who will stand unapologetically in defense of marriage and life.

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.

If we want to defend the country, we have to defend against who's coming in.
