President Donald Trump has ordered signs to be placed outside the Smithsonian National Museum of American History, to caution visitors about exhibits his administration views as "inaccurate". The Trump administration has often accused the Smithsonian Institution, the world's largest research museum, as well as other academic organisations of harbouring an anti-American bias. It says the museum's leadership team "views American history as a 'prime tool' to advance ideas of social justice and the radical transformation of our society". "This EO is a clear political overreach, driven by an ideological agenda to rewrite American history," congresswoman Melanie Stansbury, ranking member of the House Administration Committee, wrote on X. They include the National Museum of American History, the National Portrait Gallery, the American Art Museum, the National Zoo and more than a dozen others.
