I really think the most important thing I do is to protect the dignity and the integrity of the Office of the Surgeon General.

As 17th U.S. Surgeon General, I was privileged to serve as the nation's doctor. I focused much of my time on promoting proven programs and individual steps that lead to good health.

In honor of Surgeon General Koop's legacy, we should ensure that the position of surgeon general is protected from political interference, funded appropriately and nominated from the ranks of career public health professionals who merit consideration, as is done in the other uniformed services.

I am not a Hispanic candidate. I am an American candidate who happens to be of Hispanic heritage, who understands the culture, who has worked the border and has a unique understanding of those issues. But rest assured my job is to represent all Americans as a U.S. senator.

I used to be a real doctor. Now I just play one on TV.

I grew up in Harlem. My grandmother was one of the best cooks around, but the first thing she did on Sunday mornings when she started cooking a daylong meal was to take a big block of lard from the back of the refrigerator and throw it into the pan.

Because of the increasing rates of obesity, unhealthy eating habits and physical inactivity, we may see the first generation that will be less healthy and have a shorter life expectancy than their parents.

As a young surgeon in training at the University of California San Francisco General Hospital in the early '80s, my colleagues and I were inundated with an epidemic of young men with fevers, rashes, swollen lymph nodes and eventually death.

The overarching issue, really, is our surgeon general should be able to communicate transparently and honestly with the American public on all issues.

Trying to block women from getting access to contraception or defunding Planned Parenthood is completely nonsensical from a policy standpoint.

Overweight and obesity is the second leading cause of death, killing 300,000 people a year, There is not a miracle pill that will lead to weight loss.

We need stem-cell research, no question about it. It is absolutely crucial for moving our medical science forward. We are trying to harness an untapped source of energy that can provide cures and possibly even prevent disease and suffering.

I see good ideas on the Republican side as well as the Democratic side. You have to return civility and statesmanship to governance. If you don't do that, it doesn't matter what portfolio of issue you're pushing, nothing is going to get done.
