Donald Trump would end up raising taxes on middle-class families.

In this world and the world of tomorrow, we must go forward together or not at all.

We saw more evidence that [Doanld Trump] is temperamentally unfit and totally unqualified to be commander-in-chief. He trash-talked American generals, saying they had been, quote, "reduced to rubble," that's how he talks about distinguished men and women who have spent their lives serving our country, sacrificing for us. That's how he would act as commander-in-chief.

I was so shocked when Donald Trump publicly invited Putin to hack into Americans. That is just unacceptable.

I think probably [Donald Trump] is not all that enthusiastic about having the rest of our country see what the real reasons are, because it must be something really important, even terrible, that he's trying to hide.

You know, the vibrancy of the black church, the black businesses that employ so many people, the opportunities that so many families are working to provide for their kids. There's a lot that we should be proud of and we should be supporting and lifting up.

It cannot be an American fight. And I think what the president [Barack Obama] has consistently said - which I agree with - is that we will support those who take the fight to ISIS. That is why we have troops in Iraq that are helping to train and build back up the Iraqi military, why we have special operators in Syria working with the Kurds and Arabs, so that we can be supportive.
