In this Wednesday, April 22, 2020, file photo, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, speaks about the new coronavirus in the James Brady Press Briefing Room of the White House, in Washington. Three members of the White House coronavirus task force, including Fauci, have placed themselves in quarantine after contact with someone who tested positive for COVID-19, another stark reminder that not even one of the nation's most secure buildings is immune from the virus.
