Well, this is one way to distinguish himself from fellow progressive Elizabeth Warren.

Democratic presidential contender Sen. Bernie Sanders (D-Vt.) does not think he needs to come up with a plan for how to pay for Medicare-for-all, according to an interview he gave to CNBC’s John Harwood.

During the interview, which was published Tuesday, Harwood challenged Sanders on identifying revenue sources to cover the high costs of his signature health care proposal, something the Vermont senator brushed off as not urgent.

“The fight right now is to get the American people to understand that we’re spending twice as much per capita, that of course, we can pay for it. We’re paying it now in a very reactionary, regressive way. I want to pay for it in a progressive way,” Sanders responded.

“You’re asking me to come up with an exact detailed plan of how every American — how much you’re going to pay more in taxes, how much I’m going to pay. I don’t think I have to do that right now.”

Harwood pressed that fellow 2020 hopeful Sen. Elizabeth Warren (D-Mass.) is developing her own plan to pay for the health care overhaul, asking if Sanders thought that was foolish.

“I’m not saying it’s foolish. All that I’m saying is that we have laid out a variety of options that are progressive. We’ll have that debate,” the Vermont senator responded, adding, “At the end of the day, we will pay for every nickel of Medicare-for-all, and it will save the overwhelming majority of the American people, who will no longer pay premiums.”

Sanders had previously offered revenue sources that would cover about half the cost of implementing his proposal, though he and Warren faced criticism from their 2020 rivals over how they’d pay for their plan during the last debate.

Warren caved to that pressure, announcing since then that she would create and release a payment plan.

It doesn’t appear that Sanders will be following suit.
