I have been in Washington for a while now, and most things don't surprise me. The fact that twenty 6-year-olds were gunned down in the most violent fashion possible and this town couldn't do anything about it was stunning to me.

I was reminded that it is my obligation not only as an elected official in a pluralistic society, but also as a Christian, to remain open to the possibility that my unwillingness to support gay marriage is misguided.

It's up to [Angela Merkel] whether she wants to stand again and then ultimately, it'll be up to the German people to decide what the future holds. If I were here and I were German and I had a vote, I might support her.

As president, I decided that a strong, confident America could advance our national security by engaging directly with the Iranian government. We've seen the results.

Iran will for sure have pledged to the international community that it will not develop a nuclear weapon, and now will be subject to an additional protocol, a more vigorous inspection and monitoring regime that lasts in perpetuity.

I do not believe being gay or lesbian is a choice.

In the past, there have been a range of treaties that divided Congress and every administration was able to get them through.
