Stepping back from running [Donald Trump] positions is meaningless from a conflict of interests perspective. The presidency is a full-time job and he would have had to step back anyway.

I think Iran deal is on life support, I'll put it that way, but I'm not here to declare one way or the other where it will go. But I do believe it's on life support. I know the president-elect does not like the Iran deal, thinks it's really, really bad. And that's sort of the starting point on that discussion.

Walt Shaub is a true ethics hero for speaking out.

Because of President Obama's failed record on nearly every issue from the economy to the deficit to Medicare, the Obama campaign has become increasingly dirty, despicable, and desperate.

We want to repeal the ObamaCare tax. We want to save middle class families from European health care. And that's what we're going to do as a party and that's what Mitt Romney will do on day one.

One thing that the American people I think know about President Trump is that he's the boss. And over time, people are going to see that he's the guy that's going to deliver to the American people, putting America first and making the future better for everyone across the country.

It doesn't mean we're not going to be tough across the world, it doesn't mean that we're not going to always put America first in everything we do. But we have big problems in this world. And I don't think we can solve these big problems by making believe that people don't exist. They exist. We have to talk to people.
