Vermont Sen. Bernie Sanders defended his sweeping plan to overhaul America’s health insurance system, saying “Medicare for All” will reduce the nation’s health care price tag.

“What every study out there, conservative or progressive says, 'Medicare For All' will save money,” said Sanders, who came under fire for the cost of his proposal, which has been pegged at more than $30 trillion over a decade.

Facts first: Although Sanders is correct that several studies have found "Medicare for All" would reduce health care spending, at least one study published last year found the opposite.

A report from the left-leaning Urban Institute Health Policy Center showed that the nation's overall health care spending would rise by roughly $7 trillion to $59 trillion over a decade if Medicare for All goes into effect. The increase would be $720 billion for 2020 alone if the policy were enacted.

That's because more people would be insured, more benefits would be covered and more medical services would be used since there'd be no cost for care.

"You will in total spend more as a nation on health care from adding all the bells and whistles that are associated with these kinds of proposals," Linda Blumberg, an institute fellow, said when the study was published last October.
