Former Vice President Joe Biden said Monday that he was not reconsidering his opposition to single-payer health care despite the strain that the coronavirus pandemic has put on the existing health-care system.

"Single-payer will not solve that at all," Biden said during an interview on MSNBC.

Biden is running against Sen. Bernie Sanders for the Democratic presidential nomination. Biden is ahead in delegates, 1,181 to 871, out of 1,991 needed to win, according to an NBC News tracker.

Sanders' "Medicare-for-all" proposal to overhaul the health-care system and implement a single-payer, government-run system was a focus of the race even before the public health crisis erupted in the U.S. and essentially knocked both men off the campaign trail.

Biden has opposed the proposal, citing its costs, and suggested earlier in March that as president he might veto it, though his campaign later seemed to walk back the comments.

"The thing that is needed is, for example, we have a whole number of hospitals that are being stretched, including rural hospitals, they are going to need more financing. That doesn't come from a single-payer system," Biden said.

"That comes from the federal government stepping up and dealing with concerns that they have," Biden said. "The reimbursement they are going to get, how they're going to be able to move forward."

Sanders has said that the unfolding crisis has put a spotlight on the weaknesses of the current system.

The coronavirus pandemic is likely to kick millions of Americans off their health insurance as the disease's economic toll sweeps through the nation.
