The National Constitution Center (NCC) in Philadelphia has hit a rough patch after Jeffrey Rosen, its president for 12 years, stepped down unexpectedly. Rosen, aged 61, played a key role in shaping the centre’s programs and its global reputation. He was deeply involved in preparing for the 250th anniversary of US independence in July 2026. Vince Stango, 48, is now the interim president. Some insiders say Rosen lacked interest in daily management, prompting the change. But others claim board members Doug DeVos and Mike George forced Rosen out for political reasons tied to Donald Trump and the upcoming anniversary. J Michael Luttig, a retired federal judge, told the Guardian, “The two chairmen’s reprehensible actions were all about Donald Trump and the celebration of the 250th anniversary of America’s founding on July 4, 2026, and nothing whatsoever about Mr Rosen.” The NCC denies political motives. Stango said Rosen decided to step down to focus on personal scholarship and believed he had led the centre well. The centre faced internal strife with board members divided and confusion about the leadership crisis. Rosen reportedly offered to resign expecting refusal, but the executive committee accepted it unanimously. Luttig circulated emails accusing the chairmen of withholding information and forcing a vote, claims disputed by others. Despite attempts to resign, Luttig remains listed in a limited capacity as a trustee. Rosen has been named CEO emeritus. Historians praise Rosen’s strict non-partisan leadership and his contribution to the centre, seen as vital ahead of the 2026 anniversary. The NCC is a congressionally chartered non-profit dedicated to educating Americans about the US Constitution. Meanwhile, accusations swirl of political influence over the museum, amid wider efforts by Trump’s administration to control cultural institutions. George defended the leadership change, calling politics claims “absurd,” while DeVos declined comment. The NCC’s future leadership path remains uncertain as focus shifts to the major anniversary event in Philadelphia.
