Barack Obama’s former acting administrator for the Centers of Medicare and Medicaid Services (CMS) has warned that over one million Americans could die because the coronavirus was not contained.

“Currently experts expect over 1 million deaths in the U.S. since the virus was not contained & we cannot even test for it,” Andy Slavitt warned on Twitter Thursday.

“The original sin is Trump’s months long denial and his dismantling of public health and response infrastructure.”
