I have come to think we have to treat Donald Trump's tweets like Snapchat. It's just something that is going to go away. And it flies out of some region of his brain and it goes out into the ether. And usually it's on the realm of media.

There are plenty of team players in government who do whatever the leader says. There are too few difficult members, who have complicated minds, unusual perspectives, the toughness to withstand the party-line barrages and a practical interest in producing results.

People who give money in large amount in politics are basically not altruistic. They have some issue. They have some interest. It may be world peace. It may be preserving carried interest. But it's not altruistic.

What you hear in focus groups and conversations, people will give you 20 minutes of rage about how the borders are out of control. But then you start saying, practically, what are we going to do about it? What are we going to do about the 11 million here? What are we going to do to get some workers we need for the farms? Then people start having a normal conversation.

Putin is someone who has been undermining the norms of what we consider the world order since he got into power and in increasing success.

It's always dangerous to overinterpret what Donald Trump says at any one moment.

Plunder is morally wrong. It ruins your credibility.
