I think, certainly, Barack Obama has created an opportunity for America to understand that diversity is a blessing, diversity is a strength. It isn't necessarily something to be concerned about. And I think, at the end of the day, we're going to learn that this country operates best when it celebrates and surrounds itself and appreciates diversity, and doesn't shun it.

I wish I could give you all the examples over the last two years as secretary of agriculture, where I hear people in rural America constantly being criticized, without any expression of appreciation for what they do do.

Somewhere between 50 to 60 percent of the food you eat has been touched by immigrant hands, and it is fair to say some of them are not here as they should be here. But if you didn't have these folks, you would be spending a lot more - three, four or five times more - for food, or we would have to import food and have all the food security risks.

I can't give you a specific number today, in large part because the analysis upon which we would make that determination has not been completed. . . . I think it is fair to say there may be additional costs associated with a farming operation, but it is very difficult to quantify.

Food during my early years was a very difficult issue for me. I grew up in an addictive family. My mother had serious problems with alcohol and prescription drugs. I was an overweight kid. I can remember back in those days there weren't the strategies that there are today to deal with those issues.

The rise of childhood obesity has placed the health of an entire generation at risk.

What Republicans have done in my view is that they are systematically dismantling a sense of community in America.
