CNN anchor Jake Tapper reportedly recorded a show in person earlier this month after testing positive for COVID-19, to the exasperation of some of his staffers.

Tapper tested positive on May 9 shortly before his show, The Lead, was set to air and remained in the building to finish his show solo in a flash studio, sources told the Daily Beast. CNN has defended his actions, arguing he adhered to company protocol.

“When he was notified of the positive result, he asked CNN execs what to do and then followed it to the letter — he double-masked and isolated, did the show solo in a flash studio, and went home immediately after,” a spokesperson for CNN told the outlet.
