On March 12, 2020, one day after COVID-19 was declared a pandemic, the CBS Broadcast Center was closed for disinfection after two employees tested positive for COVID-19. Production of WCBS newscasts was assumed by KCBS-TV, while "CBS This Morning" was moved to CBS News's Washington studio (used for the "CBS Evening News" since December). The Broadcast Center reopened on a limited basis on March 14, 2020, starting with the Saturday edition of "CBS This Morning" from Studio 57; on March 18, ViacomCBS announced that its operations would again temporarily relocate from the Broadcast Center, with "CBS This Morning" moving to the set of "The Late Show with Stephen Colbert" at the Ed Sullivan Theater and KCBS-TV again producing WCBS-TV's newscasts. Since March 20, WCBS-TV newscasts have been presented from the studios of New York Yankees and Brooklyn Nets broadcaster YES Network in Stamford, Connecticut, before moving back again to the Broadcast Center, beginning on April 17 with the morning newscast. On the June 21, 2020 broadcast of 60 in 6, Seth Doane partially covered the Broadcast Center's exposure to COVID-19 in a piece titled "CBS News Battles COVID-19". The piece mentions that CBS News flew in staffers, including those located in Seattle and Rome in early March 2020 to begin filming promotional material for 60 in 6, which brought COVID-19 positive individuals in close contact with CBS employees which resulted in the shutdown of the CBS Broadcast Center.
