Due to a partial government shutdown, National Archives' facilities were closed on Saturday. U.S. President Donald Trump said Saturday that he was negotiating with the Democrats to end a partial government shutdown, but "it could be a long stay" due to continued discrepancy on his long-time demand for a border wall.
