If we can't meet with our friends, I don't know how we're going to lead the world in terms of dealing with critical issues like terrorism.

My wife has been my closest friend, my closest advisor. And ... she's not somebody who looks to the limelight, or even is wild about me being in politics. And that's a good reality check on me. When I go home, she wants me to be a good father and a good husband. And everything else is secondary to that.

These kinds of tragedies [like shooting in Fort Lauderdale] have happened too often during the eight years that I've been president. The pain, the grief, the shock that they must be going through is enormous.

In businesses that can create the new energy economy of the future. In policies that will lift wages and will grow our middle class. These are the policies I have fought for my entire career.
