A rare reunion of American political leaders is expected to take place this week as Presidents Biden, Clinton, and Bush are reportedly planning to attend the opening celebration of the Obama Presidential Center in Chicago.

According to a report published Wednesday by the Chicago Sun-Times, all three presidents are expected to join President Barack Obama for the landmark event. The newspaper cited a source familiar with the plans for the ceremony.

The gathering is also expected to include several former first ladies. The report said Laura Bush, Hillary Clinton, and Jill Biden will be among those attending the festivities.

The Obama Presidential Center is scheduled to officially open on Thursday. Organizers have planned a major celebration featuring performances by a number of acclaimed entertainers and artists.

Valerie Jarrett, chief executive of the Obama Foundation, said the opening ceremony is being designed as a unique and uplifting experience that goes beyond a traditional ribbon-cutting event.

“will be unlike any other — filled with music, performances, and hope.”

Jarrett said the program is intended to celebrate the center’s mission while encouraging people to believe they can make a difference in their own communities.

“The Grand Opening Ceremony will reflect a spirit of inspiration and joy, with a big boost from the performers who are sharing their talent with us. We hope to inspire people everywhere to believe in their power to bring change home.”
