We have now just enshrined, as soon as I sign this bill, the core principle that everybody should have some basic security when it comes to their healthcare.

We have to ensure free and open exchange of information. That starts with an open internet. I will take a backseat to no one in my commitment to network neutrality. Because once providers start to privilege some applications or websites over others then the smaller voices get squeezed out and we all lose. The internet is perhaps the most open network in history, and we have to keep it that way.

On the one hand information is moving quick or the way in which people consume information is changing so fast. Clearly this worked for [Donald Trump], and it gives him a direct connection to a lot of the people that voted for him.

When you take on the position of president, you are committing yourself to, first and foremost, protecting the American people. You are accepting an institutional role that requires you to make hard decisions and hard choices, and as a consequence you have to take your moral sense and not put it aside.
