For weeks, the coronavirus has been closing in on the Oval Office.
In late March, White House press secretary Jen Psaki tested positive for the virus, her second breakthrough infection. A few weeks later, an outbreak at the annual Gridiron Club dinner seeded infections among House Speaker Nancy Pelosi and three members of President Biden’s cabinet. And on Tuesday, Vice President Kamala Harris tested positive at the White House and had to cancel a meeting with Biden.
