I think that there is a particular mindset that was on display in the run-up to the Iraq war that continues to this day. Some of the folks who were involved in that decision either don't remember what they said or are entirely unapologetic about the results, but that views the Middle East as a place where force and intimidation will deliver on the security interests that we have, and that it is not possible for us to at least test the possibility of diplomacy.

For all the noise and anger that too often surrounds the immigration debate, America has nothing to fear from today's immigrants. They have come here for the same reason that families have always come here-for the hope that in America, they could build a better life for themselves and their families. Like the waves of immigrants that came before them and the Hispanic Americans whose families have been here for generations, the recent arrival of Latino immigrants will only enrich our country.

We need to steer clear of this poverty of ambition, where people want to drive fancy cars and wear nice clothes and live in nice apartments but don't want to work hard to accomplish these things. Everyone should try to realize their full potential.

I've enjoyed the conversations that we've had. [Donald Trump] is somebody who I think is not lacking in confidence.

Today, about 40 percent of America's carbon pollution comes from our power plants. There are no federal limits to the amount those plants can pump into the air. None. We limit the amount of toxic chemicals like mercury, and sulfur, and arsenic in our air and water, but power plants can dump as much carbon pollution into our atmosphere as they want. It's not smart, it's not right, it's not safe, and I determined it needs to stop.

Sometimes it may seem as if progress is stalled but what history of post-war Germany shows is that strength and determination and focus and adherence to the values that we care about will result in a better future for our children and our grandchildren.

I don't believe we can get very far, with leaders who write off half the nation as a bunch of victims who never take responsibility for their own lives.
