Three senior White House officials tasked with guiding America's response to the coronavirus pandemic are now in self-isolation - after coming into contact with someone who had tested positive for the disease.
79-year-old Anthony Fauci, a high-profile member of the White House coronavirus response team, is considered to be at relatively low risk based on the degree of his exposure, according to a representative for the National Institute of Allergy and Infectious Diseases.
Fauci has tested negative for COVID-19 and he will continue to be tested regularly according to an emailed statement.
Robert Redfield, the director of the Centers for Disease Control and Prevention will also be working remotely for the next fortnight, following a "low-risk exposure" on Wednesday (May 6) to a person at the White House who has COVID-19.
U.S. Food and Drug Administration Commissioner Stephen Hahn tested negative to the virus but is continuing to self isolate.
Fauci, Redfield and Hahn were all due to testify to a Senate committee on Tuesday (May 12) - looking at steps that states and the federal government are taking to reopen businesses and schools after coronavirus shut-downs.
