On Friday, The Washington Post published a story about the Archive’s “Rightfully Hers: American Women and the Vote,” exhibit that featured a photo from the 2017 Women’s March, held the day after President Donald Trump was inaugurated. The picture was altered to blur out multiple protest signs that criticized Trump and made reference to women’s body parts.
“We made a mistake,” an Archive spokesperson tells TIME in an emailed statement. “As the National Archives of the United States, we are and have always been completely committed to preserving our archival holdings, without alteration… We apologize, and will immediately start a thorough review of our exhibit policies and procedures so that this does not happen again.”
In one instance, a sign on the photo was digitally altered to blur the word “Trump” on a sign that read “God Hates Trump,” according to the Post. The word “vagina” was blurred in another sign that read “If my vagina could shoot bullets, it’d be less REGULATED.”
An Archive spokesperson told the Post that it had altered the photo “so as not to engage in current political controversy,” and to make sure the exhibits were appropriate for children.
The Archive’s decision was met with criticism from historians and free speech groups.
“The government can’t airbrush history or erase women’s bodies from it,” said ACLU deputy legal director Louise Melling in a statement. “It is the job of the National Archives to document history, not alter it to serve the President’s ego.”
An archive spokesperson tells TIME the display has been removed and will be replaced with unaltered images. “This photo is not an archival record held by the National Archives, but one we licensed to use as a promotional graphic. Nonetheless, we were wrong to alter the image.”
