Over the years, we have lost millions of decent paying jobs. These trade agreements have forced wages down in America so the average worker in America today is working longer hours for lower wages.

I also believe that we have an extraordinary opportunity for the United States and European Union to lead the world in developing and implementing new and more efficient technologies - smart electrical grids and electrical vehicles.

Our lives are a mixture of different roles. Most of us are doing the best we can to find whatever the right balance is . . . For me, that balance is family, work, and service.

All people deserve to be treated with dignity and have their human rights respected, no matter who they are or whom they love.

Lots of people commit crimes and don't get arrested. That's not the measure. But if you're going to be the president of the United States, we're reasonably going to put you under a microscope. And Donald Trump's tax behavior is absolutely important to understanding, is he qualified, is he morally fit, is he capable, is he trustworthy to have everything from the powers of federal law enforcement to the nuclear codes?

Every presidential candidate for decades has released his tax returns, and I've released 33 years of my tax returns. The American people deserve to know about our taxes. And so Donald Trump is standing in the way of precedent that goes back on both sides of aisle Democrats and Republicans, and he clearly has something that he doesn't want us to see.

You just have to sort of figure out how to - getting back to that word, "balance" - how to balance the public and the private efforts that are necessary to be successful, politically, and that's not just a comment about today. That, I think, has probably been true for all of our history.
