SEN. BOB CASEY (D-PA): What we need on health care, first and foremost, is to protect the Affordable Care Act and protect Medicaid. They're my top two priorities. In addition to that, we need hearings on a whole range of issues. If some people want to have hearings on Medicare-for-all, we should explore that. We should also explore whether Medicaid itself can be used as an option on the exchanges. How about Medicare from 55 and up. So there are a lot of ideas. What we have not had enough of, is a close examination of any of these new proposals. That is what is needed here. So I'm going to need to know a lot more before we make that kind of a change.

JIM SCIUTTO (CO-HOST): A lot -- a lot of tweeting about it, I was going to say, but not a lot of actual discussion of the details. I wonder, though, if you are concerned with a promise, a bold promise like that from someone who is getting a lot of attention as a possible Democratic candidate? Are you concerned that the party is being pulled too far to the left to the point where it cannot mount a credible challenge against President Trump in 2020?
