White House press secretary Jen Psaki acknowledged that there have been prior breakthrough cases among White House staffers in addition to the fully vaccinated official who CNN reported on Tuesday tested positive for Covid-19.

“There have been. I will say that we, according to an agreement we made during the transition to be transparent and make information available, we committed that we would release information proactively if it is commissioned officers,” Psaki said when asked if there had been other breakthrough cases among White House staff.

A White House “commissioned officer” is any official who has a version of “assistant to the President” in their title.
