I want to close the online loophole and the gun show loophole.

The Republicans can't go after Donald Trump where I think he needs to be criticized.

The episodic, reactive, almost frantic pace of what is broadcast makes children feel and act frantic and shortens their attention spans and their patience for activities that take time and problems that don't yield immediate solutions.

I made policy decisions based on what I thought was right that keep Americans safe and to protect U.S. interests abroad. No wild political attacks by Donald Trump is going to change that.

One thing we know for sure is that change is certain. Progress is not. Progress depends on the choices we make today for tomorrow and on whether we meet our challenges and protect our values.

The point is [Donald] Trump goes way too far. He then demonizes Muslims - American Muslims. He wants to ban all Muslims from everywhere in the world, including the new mayor of London who has spoken about this from coming to our country.

There is a sense that things, if you keep positive and optimistic about what can be done, do work out.
