Last month, the National Archives and Records Administration apologized for doctoring a photo of the 2017 Women’s March to remove criticisms of President Trump. The shocking revelation that the agency had altered the image was first reported in The Washington Post. In an exhibit called “Rightfully Hers: American Women and the Vote,” the National Archives had displayed a large image of the first Women’s March. But signs referencing Trump had been blurred to remove his name — including a poster reading “God Hates Trump” and another reading “Trump & GOP — Hands Off Women.” Other signs in the photo referencing female anatomy were also blurred. The National Archives initially stood by its decision to edit the photo, telling The Washington Post that the changes were made “so as not to engage in current political controversy.” For more, we turn to a historian who says this was only the latest example of “a great and growing threat to our nation’s capacity to protect and learn from history.” The National Archives reportedly is allowing millions of documents, including many related to immigrants’ rights, to be expunged. We speak with Matthew Connelly, professor of history at Columbia University and principal investigator at History Lab. His recent piece for The New York Times is headlined “Why You May Never Learn the Truth About ICE.”
