Donald Trump on Friday ordered the interior department to display signs in front of the Smithsonian National Museum of American History that accuse the institution of inaccuracy. The order says the signs "shall notify visitors that the museum exhibits should be renovated consistent with the findings in the report". The signs should direct the public to other places where they can get better American history information, the order says. "Political interference in professional museum work threatens the accuracy of historical interpretation and erodes public trust in one of our nation's most important institutions." The National Museum of American History declined to comment.
