The combat [with ISIS] on the ground must be done by Muslim troops with our support. We must not get involved in perpetual warfare in the Middle East.

To be honest with you, I worry about concentration of ownership in media, where you have a handful of media conglomerates largely controlling what we see, hear and read.

I'm a United States senator, and I have a responsibility to the people of my state - also to the people of this country.

When we are fighting for huge stakes - we're fighting for the future - future of the planet in terms of climate change. We're fighting for the future of American democracy.

Real change never occurs from the top on down, [but] always from the bottom on up.

I voted against the war in Iraq. I voted against the first Gulf War. I think war is the last resort - the last option of a great military power like us. I think that we need to focus on building coalitions. Yes, ISIS must be destroyed. But it should be destroyed by a coalition of Muslim nations on the ground with the support of the United States and the other major powers in the air and in training the troops there.

But because media is what media is today, any stupid, absurd remark made by Donald Trump becomes the story of the week. Maybe, just maybe, we might want to have a serious discussion about the serious issues facing America. Donald Trump will not look quite so interesting in that context.
