The Iranian regime supports violent extremists and challenges us across the region. It pursues a nuclear capability that could spark a dangerous arms race and raise the prospect of a transfer of nuclear know-how to terrorists. Its president denies the Holocaust and threatens to wipe Israel off the map. The danger from Iran is grave, it is real.

The Middle East is obviously an issue that has plagued the region for centuries.

Germany, South Korea - these are all countries that are investing massively in education. We've got to do the same thing in America.

There are always things that I think I wish I could have done better.

Call Loretta Lynch for a vote. Get her confirmed. Put her in place. Let her do her job.

Robin Williams was an airman, a doctor, a genie, a nanny ... and everything in between. But he was one of a kind.

I think that Mr. Snowden raised some legitimate concerns. How he did it was something that did not follow the procedures and practices of our intelligence community. If everybody took the approach that I make my own decisions about these issues, then it would be very hard to have an organized government or any kind of national security system.
