The C.D.C. is not involved in contact tracing from the Rose Garden ceremony.
The White House has not sought help from the Centers for Disease Control and Prevention to trace the contacts of people who attended a celebration in the Rose Garden on Sept. 26 for Judge Amy Coney Barrett, according to a federal official familiar with the matter.
Dr. Sean Conley, the White House physician, told reporters on Saturday that his team was working with the agency to trace contacts. But according to the federal official, while the C.D.C. had a team of experts on standby to help the White House, it has not been approached to do so.
In an interview Sunday on the CBS program Face the Nation, Dr. Scott Gottlieb, a former commissioner of the Food and Drug Administration, also offered evidence suggesting that no robust contact tracing effort was underway. Dr. Gottlieb said he had spoken to several officials who attended the Rose Garden event and who had not been spoken to by any contact tracers.
I think they have an obligation to understand how the infection was introduced into that environment, he said of the White House. There doesnt seem to be a very concerted effort underway.
