Former President Barack Obama on Wednesday vowed to shrink the size of his 60th birthday bash “significantly,” days before a number of high-profile celebrities were set to convene at the Democrat’s luxury home.

On Saturday, Obama was expected to host 475 confirmed guests, including Oprah Winfrey and George Clooney, along with 200 staff working the event, at the former president’s $12 million Martha’s Vineyard mansion in Massachusetts. Obama has promised to nix attendees who aren’t “family and close friends” as the party was the subject of scrutiny from many after coronavirus cases have surged in the United States over the last few weeks.
