Crede Bailey, the director of the White House security office, was the most severely ill among dozens of Covid-19 cases known to be connected to the White House. Bailey’s family has asked the White House not to publicize his condition, and President Donald Trump has never publicly acknowledged his illness. The White House declined to say whether Trump has contributed to the effort. Bailey’s office handles credentialing for access to the White House complex and works closely with the U.S. Secret Service on security measures.
