Speaking from the Rose Garden, Trump said, “I am officially declaring a national emergency.” He said the presidential directive will make available more than $50 billion for state and local governments to respond to the coronavirus outbreak.

“Trump said he was also giving Secretary of Health and Human Services Alex Azar emergency authorities to waive federal regulations and laws to give doctors and hospitals “flexibility” in treating patients,” the Associated Press reported.
