All living former U.S. presidents attend the opening of Barack Obama’s presidential centre in Chicago, according to multiple reports. The events feature a star-studded public programme for the centre’s launch, with a turnout that includes the living ex-presidents. Across the accounts, the notable common point is the absence of Donald Trump, the current White House occupant at the time of the opening. While the sources emphasise the presence of former presidents and other celebrities, they do not provide additional details on specific attendees or the full list of participants beyond the broad description of a star lineup. The reports frame the occasion as a significant moment for the Obama presidential library and centre, held in Chicago, and highlight that every living former president is present except Trump. Overall, the articles converge on the same core facts: the opening takes place in Chicago, the living ex-presidents attend, and Donald Trump does not.
