Most Republicans are not prepared to stand up to the fossil fuel industry because they get a lot of their campaign funds from the Koch brothers and other people in the fossil fuel industry. That tells me why we have to reform our campaign finance system.

Do not tell me that I have not shown courage in standing up to the gun people, in voting to ban assault weapons, voting for instant background checks, voting to end the gun show loophole and now in a position to create a consensus in America on gun safety.

What I do know is that drones are a modern weapon. When used effectively, when taking out ISIS or terrorist leaders, that's pretty impressive. When bombing wedding parties of innocent people and killing dozens of them, that is, needless to say, not effective and enormously counterproductive. So whatever the mechanism, whoever is in control of that policy, it has to be refined so that we are killing the people we want to kill and not innocent collateral damage.

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