Michael Bloomberg:

Well, I think the president has to learn the job, and he's still doing that. He's doing it slower than I would have thought.

He has to build a team, and he's really not done that. And now it's harder for him to attract good people.

But the bottom line is, this president, as all presidents, need a team, and let them make decisions. You have got to hire people and give them authority to go along with responsibility. And you have got to hire people who are experts in each facet of government, rather than people who just happen to agree with your political point of views.

And he's not separated out the politics from the knowledge that we need.

And to sit there and say to CDC, the Centers for Disease Control, you can't use certain words, or we can't talk about climate change, we can't talk about certain things that are politically not what the president believes in, but you can't manage science.

We're almost going back to the Dark Ages of saying what science is, what things they can look at, and what their conclusions have to be from a political point of view, regardless of whether the science gets there.

The president has to understand that he's the president of all the people and that his political views, he has a right to those — and there is nothing wrong with him trying to push those — he was elected by 63-odd million people. But certain things, you just have to do based on the facts and have experts, nonpolitical experts, do it.
