On the eve of the 250th anniversary of the signing of the Declaration of Independence, the Trump administration is rewriting history by wielding the tools of censorship and erasure. Notably, America continued to reveal itself, as Jill Lepore has written in her prize-winning book “These Truths: A History of the United States.”Because historians debate American history by offering new facts or reinterpretations of old ones, new names enter the pantheon of American heroes. President Trump has issued an executive order requiring a review of its exhibits, and he has identified specific exhibits he does not like, most of which are exhibits about racial minorities and LGBTQ+ history. Politicians and pundits regularly frame their campaigns and opinions around their visions of the country and its history. History informs that debate, but only if the government does not censor what can be taught, written and presented in museums.
