Sen. McCain and Gov. Palin are sowing the seeds of hatred and division, and there is no need for this hostility in our political discourse.

I would say to a young person: continue to study. Study what is taking place in your community, in your neighborhood, maybe at your school.

Young people can understand, and must understand, that we had success, we had failures, but we never gave up. We never gave in. We never became bitter. We didn't hate. We continued to press on. And that's what we're saying: There are some ups, there are some downs, and when you're not down, you must have the capacity and the ability to get up and keep going.

That issue has been resolved for years now, and it's been resolved for at least two years in Donald Trump's mind. And to bring that up as justification for John Lewis questioning the legitimacy of a democratic activity that is - has been around since the beginning of our country is wrong.

But you have to have hope. You have to be optimistic in order to continue to move forward.

I think all three of those men [James Mattis, Mike Pompeo and Rex Tillerson] that you just mentioned, depending on what deal was struck with Russia, depending on what terms the deal would have and what incremental steps we would have to take and measurements that we would have to take with potentially Russia in a deal, some of those positions could change, and some of President-elect Donald Trump's positions could change depending on what deal could be struck.

I think putting the United States down across the world is not something that a responsible person does.
