During a wide-ranging interview with CNBC's John Harwood published Tuesday, Sanders dismissed the idea that he should explain in detail how he'd pay for his signature health plan.

"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," Sanders said.

Warren was a co-sponsor of Sanders’s bill in the Senate, and during one of the presidential debates said she is “with Bernie” on health care.

Sanders has been upfront that Medicare for All would involve raising taxes on the middle class as well as on the wealthy but has not fully explained where the revenue for his plan would come from.

Sanders last spring released a list of financing suggestions for his updated Medicare for All legislation, but the list would only cover about half the cost. A conservative group estimated Medicare for All would cost about $33 trillion over a decade, but Sanders has said that amount is inflated.

When pressed by Harwood about where he would get the other half of the funding, Sanders said he was confident the plan would be fully paid for.

“All that I’m saying is that we have laid out a variety of options that are progressive. We’ll have that debate,” Sanders said. “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.”

Medicare for All supporters say that while taxes may increase, the plan would save most Americans money in the long term by using the federal government to force health care providers to lower prices.
