It was more than just “a copy”. The Constitution requires the President to provide a summary of “the state of the Union, from time to time”. It looked to me like what Nan got was the official parchment version required by the Constitution. I don’t think it should be replaced. It should remain as a monument to the petty, vindictive failure that the Speaker really is.
Looked like plain white paper to me. Perhaps larger than 81/2 X 11 but not parchment. I think they stopped using parchment about 200 years ago.
