Each year, the National Archives organizes events marking the Fourth of July, the birthday of the United States of America. This year, the National Archives prepared an especially fitting exhibition. Entitled “Amending America,” it is a story about thousands of failed attempts to change the U.S. Constitution, a succinct body of fundamental principles and precedents by which America is governed. VOA’s Nikoleta Ilic recently caught up with National Archives curator, Christine Blackerby.
