My experience is that our intelligence officials try to do the right thing, but even with good intentions, sometimes they make mistakes. Sometimes they can be overzealous.

It was unknowable then, but so much of the progress that would define the 20th century, on both sides of the Atlantic, came down to the battle for a slice of beach only six miles long and two miles wide.

Michelle, I love you. The other night, I think the entire country saw just how lucky I am. Malia and Sasha, you make me so proud…but don't get any ideas, you're still going to class tomorrow. And Joe Biden, thank you for being the best Vice President I could ever hope for.

I know many of you are hurting and angry about the economy, and I don't blame you. It's the worst economy since the Great Depression. When consumers can't buy and businesses won't expand for lack of customers, the government has to be the purchaser and employer of last resort. We learned that in the Great Depression, but Republicans obviously didn't - and they've blocked every jobs program I've offered.

I think back to the day I drove Michelle and a newborn Malia home from the hospital nearly 11 years ago - crawling along, miles under the speed limit, feeling the weight of my daughter's future resting in my hands. I think about the pledge I made to her that day: that I would give her what I never had - that if I could be anything in life, I would be a good father. I knew that day that my own life wouldn't count for much unless she had every opportunity in hers.

The biggest threat, when it comes to climate change and pollution, isn't going to come from us because we only have 300 million people. It's going to come from China with over 1 billion people and India with over 1 billion people.

Like Joe Biden and so many other Americans, I've lost people I love deeply to cancer. I've heard often from those whose loved ones are suffering from Alzheimer's, addiction, and other debilitating diseases. Their heartbreak is real, and so we have a responsibility to respond with real solutions.
