I think it would help tremendously to have a senator that knows where jobs come from, that knows how to create them, that knows how to bring them back and, importantly, knows what it means to manage billions of dollars' worth of expenses and cut billions of dollars' worth of expenses.

As president, I will ensure that the United States is the global energy powerhouse of the 21st century.That means reinstating the Keystone XL Pipeline that President[Barack] Obama rejected. It also means rolling back the regulations from this administration that limit our ability to find resources by imposing regulations on hydraulic fracturing and our ability to be energy independent by regulating drilling on federal lands. As president, I will make America an energy leader through technology and innovation.

One of the things I would immediately do [as Commander in Chief ], in addition to defeating them here at home, is bring back the warrior class - Petraeus, McChrystal, Mattis, Keane, Flynn. Every single one of these generals I know. Every one was retired early because they told President [Barack] Obama things that he didn't want to hear.

I think more to the point, these pivotal times means something other than a politician. I understand the economy. I understand the world. I have a lot of foreign policy experience. I understand bureaucracies. I understand technology, and I understand leadership.

I have met Vladimir Putin, and I know his ambition will not be detoured by a gimmicky red, reset button.

Make the choice to do something because it engages your heart as well as your mind. Make the choice because it engages all of you.

Look, you need technical skills to run a company.
