The thing that has disturbed me most about the Russian hacking episode is - and the thing that surprised me most has not been the fact of Russian hacking. The cyber world is full of information gathering, you know, propaganda, et cetera. I have been concerned about the degree to which, in some circles, you've seen people suggest that Vladimir Putin has more credibility than the U.S. government. I think that's something new.

Change will not come if we wait for some other person or some other time. We are the ones we've been waiting for. We are the change that we seek.

A better politics is one where we appeal to each other’s basic decency instead of our basest fears.

When it comes to immigration, I have actually put more money, under my administration, into border security than any other administration previously. We've got more security resources at the border - more National Guard, more border guards, you name it - than the previous administration. So we've ramped up significantly the issue of border security.

If people find that controversial then I would just refer them to the Sermon on the Mount.

If we have the kinds of confirmation that we need, we will once again work with the international community and the organization charged with monitoring compliance by the Syrian government, and we will reach out to patrons of Assad like Russia to put a stop to it.

No challenge poses a greater threat to future generations than climate change.
