Biden's plan is notable mostly for its explicit rejection of Medicare for All, the single-payer plan proposed by Sen.
But it was Sanders's staff who really shot back Biden.
USA presidential candidate Bernie Sanders, pushing an ambitious "Medicare for All" health plan that has split Democratic White House contenders, will urge his rivals on Wednesday to reject campaign donations from the health insurance and pharmaceutical industries.
45 percent that Biden has the best chance of beating President Donald Trump, with 12 percent for Sanders, 11 percent for Harris and 8 percent for Warren. The senator insists his plan would be a net financial benefit for most households by eliminating their insurance and co-pay costs, even if their taxes go up.
To be fair, Biden has argued that it will be easier to expand ACA than to build a Medicare-for-all system from scratch.
"Because exactly four years ago right now there was a messy, crowded primary, with too many candidates, people who were totally unelectable, and Donald Trump was one of them and ended up winning", he pointed out.
The comments in Tuesday's interview came in a discussion regarding potential debate strategies should Biden earn the Democratic nomination and face the President in the general election.

Democratic 2020 U.S. presidential candidate and former U.S. Vice President Joe Biden speaks at a campaign stop at Mack's Apples in Londonderry, New Hampshire, U.S., July 13, 2019. For such activists, ObamaCare is the clunker they drive to work; Medicare-for-all - or something like it - is the shiny, sleek sports vehicle they want to own someday. "We should be building from what we have", he said last week.
"It's very different than turning to someone on a stage who says something that's so off the wall to me because I don't want to attack anyone on stage, that's not what I intend to do", Biden said. "How did we end up where we are?" said the Vermont senator.
Nine years after the Affordable Care Act was passed under the Obama administration, Americans are still more likely to support than oppose the law, 48% to 30%, according to an April poll from The Associated Press-NORC Center for Public Affairs Research, though a sizable share doesn't take either side. Minnesota Sen. Amy Klobuchar and Hawaii Congresswoman Tulsi Gabbard didn't register, falling from 2 percent and 1 percent, respectively.
"I think the second debate could make or break Biden", he said.
