Bernie Sanders blamed President Trump for some deaths from the coronavirus pandemic, crossing a line that Joe Biden refused to.

"His inaction has cost the lives of many, many Americans," Sanders said on The View on Wednesday.

"He is the most dangerous president in the modern history of the country, a narcissist, somebody who thinks he knows something when he often doesn't know anything," the Vermont senator and Democratic presidential candidate added.

Sanders, 78, also said Trump "downplayed the nature of this pandemic from the very beginning — 'Don't worry, it's all going to be over by April, we only have a few cases' — instead of rallying the American people, instead of rallying the scientific community, instead of educating the American people about the need for social distancing and the other things that we have to do."

The former vice president and likely Democratic presidential nominee has refused to blame Trump directly for deaths resulting from the respiratory illness.

When asked Sunday whether "there is blood on the president’s hands considering the slow response," Biden said that was "a little too harsh." On Tuesday, when asked whether Trump is "is responsible for the deaths of Americans," Biden dodged the question.

"President Trump is not responsible for the coronavirus. But he is responsible for using all of the power at his disposal to deal with this virus," he said.

Biden has, though, blamed Trump for a dramatic rise in jobless claims.

"The harsh reality is that at least 3 million people now don’t have jobs because our president didn’t do his job when it mattered," Biden said in a statement last week.
