Biden to outline plan to curb coronavirus Delta variant as cases grow

White House spokeswoman Jen Psaki told reporters traveling with Biden aboard Air Force One that he will lay out the six-pronged strategy 'working across the public and private sectors to help continue to get the pandemic under control.' Asked about possible new mandates, Psaki said the White House would offer more details later about the plan and acknowledged that the federal government cannot broadly mandate that Americans get vaccinated.
