CNN interrupted its live coverage of a White House briefing by Vice President JD Vance on Thursday in order to switch to special programming covering the grand opening of the Obama Presidential Center in Chicago.

Following the transition, anchors Wolf Blitzer and Sara Sidner took over the broadcast from Chicago, where thousands of attendees had gathered for the opening event.

The ceremony focused on the unveiling of the Obama Presidential Center, a major cultural and historical project associated with former President Barack Obama and former First Lady Michelle Obama.

Blitzer described the occasion as a historic moment, while Sidner reported a highly energized atmosphere at Jackson Park, a location closely connected to Obama's early political career.
