When you lead change, sometimes you get arrows in your back. I mean, that's just the way the real world is.

Hillary Clinton failed to mention that her agreement with a precipitous withdrawal and declaration of victory in 2011 helped left swaths of territory and weaponry from ISIS. She failed to mention that she described Bashar al-Assad as a positive reformer and opened an American embassy. She failed to mention a complete failure strategy in Libya, which now is enabling ISIS to move into Libya.

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.

We need a different kind of leadership in the White House that understands how to get bureaucracies competent again.

I know why jobs go, and I know why they come.

Some of this is bureaucratic ineptitude and a great deal of this is an administration that doesn't understand the urgency of the situation, and therefore this [Barack Obama] administration has not reached out actively to the private sector and said, we need help.

I'm happy to tell you that having been through surgery and chemotherapy and radiation, breast cancer is officially behind me. I feel absolutely great and I am raring to go.
