Democratic presidential candidate Joe Biden criticized President Donald Trump's reaction to the coronavirus outbreak, using it as a rebuke to the president's derision toward the former vice president's ability to lead.

"This is a guy who doesn't know what he's doing," Biden said on “Fox News Sunday“ to host Chris Wallace. "He doesn't know how to run the country; he is making us more unsafe the way he is responding to the coronavirus; he has done virtually nothing well that I can see."

Biden's remarks come after he gained a much-needed victory in the South Carolina primary and as the administration works to straighten its messaging on the growing global heath threat. The first reported U.S. death to coronavirus occurred Saturday in Washington state, and the Trump administration announced the release of testing kits for thousands of patients to prepare for a possible outbreak in the country.
