Democratic presidential front-runner Joe Biden said he feels "frustration” with the U.S. coronavirus response and that it’s his role to say what he believes President Donald Trump needs to do.

"If I see something that’s not happening, I think it’s my obligation to step up and say ‘this is what we should be doing,’” Biden said Sunday on NBC’s "Meet the Press.”

The former vice president said that if he were in office he would be using the Defense Production Act far more broadly than Trump has. He said he would not only compel General Motors Co. to build ventilators, as Trump has, but increase the production of personal protective equipment for health-care workers. He said he would also be thinking about the next round of economic stimulus.
