When our embassy is attacked in Benghazi by terrorists and there is no response, you get more bad behavior. When Russia invades Ukraine and there is no response, you get more bad behavior. When Syria crosses the red line and there is no response, you get more bad behavior. When Iran launches tests of ballistic missiles and there is no response, you get more bad behavior. When North Korea attacks Sony Pictures and there is no response, you get more bad behavior. In other words, Mrs. Clinton, you cannot lead from behind. We must respond when we are attacked or provoked.

Fannie Mae and Freddie Mac - two bloated and corrupt government-sponsored programs - contributed heavily to the crisis.In order to prevent another crisis, we need to do what we should have done years ago - reform Fannie Mae and Freddie Mac.

Thousands of community banks have gone out of business.

Like Hillary Clinton, I too have traveled hundreds of thousands of miles around the globe. But unlike her, I have actually accomplished something.

Leadership is not about a title, degree or level. Anybody can lead at any time.

Leadership is all about unlocking the potential in others.
