If we choose only to expose ourselves to opinions and viewpoints that are in line to our own, we become more polarized, more set in our own ways. It will only reinforce and deepen the political divides in our country. But if we choose to actively seek out information that challenges our assumptions and beliefs, perhaps we can begin to understand where the people who disagree with us are coming from.

The degree of polarization that currently exists in Washington is such where I think it's fair to say if I presented a cure for cancer, getting legislation passed to move that forward would be a nail-biter.

I do not accept that we cannot find a common sense way to preserve our traditions, including our basic second amendment freedoms and the rights of law abiding gun owners, while at the same time reducing the gun violence that unleashes so much mayhem on a regular basis.

The program grew out of a desire to address a gap identified after 9/11 ... The program does not involve the NSA examining the phone records of ordinary Americans. Rather, it consolidates these records into a database that the government can query if it has a specific lead - phone records that the companies already retain for business purposes.

Today we continue a never ending journey to bridge the meaning of those words with the realities of our time.

I do want to once again speak directly to the Iranian people. Yours is a great civilization with a vibrant culture that has so much to contribute to the world - in commerce and in science and in arts. For decades, your government's threats and actions to destabilize your region have isolated Iran from much of the world, and now our governments are talking with one another. Following the nuclear deal, you, especially young Iranians, have the opportunity to begin building new ties with the world.

And I’ve said this all across the country when I talk to parents about education, government has to fulfill its obligations to fund education, but parents have to do their job too. We’ve got to turn off the TV set, we’ve got to put away the video game, and we have to tell our children that education is not a passive activity, you have to be actively engaged in it. If we encourage that attitude and our community is enforcing it, I have no doubt we can compete with anybody in the world.
