The festivities surrounding Joe Biden’s inauguration are set to officially begin Saturday, with a concert celebrating “diversity,” followed by another four days packed with anti-Trump Hollywood celebrities, including Eva Longoria, Kerry Washington, John Legend, Kal Penn, and Debra Messing.

On Saturday, the celebration will officially kick off with “America United: An Inauguration Welcome Event Celebrating America’s Changemakers.” The inauguration committee said the concert will “celebrate America, reflect and honor our history, and highlight the incredible diversity of the nation.” It will feature appearances by anti-Trump celebrities Whoopi Goldberg, Netflix’s Atypical actor Nik Dodani, actress Cristela Alonzo, and actor Darren Criss.

Other concerts leading up to inauguration day include “United We Serve,” which will honor the National Day of Service, on January 18, and feature appearances by Diane Warren, Lynn Whitfield and Bebe Winans; and a nationwide COVID-19-themed memorial event on January 19.

Another inauguration fundraiser set for Friday will feature cast members from the TV series The West Wing, Scandal, and Designated Survivor. Actor and former Obama staffer Kal Penn will host the event.
