More than 2,000 journalists, celebrities and politicians, including President Biden, are set to descend on the White House Correspondents’ Association dinner this weekend in what is shaping up to be a major test of whether large gatherings can be safely held at this stage of the pandemic.

Organizers say they are committed to holding an event that significantly reduces the risk of coronavirus infections, pointing to vaccine and testing requirements that were strengthened after a dinner hosted by Washington’s Gridiron Club this month was linked to at least 85 infections that sickened Cabinet members, reporters and other guests.
