If the first sentence named Gorsuch instead, and the same typeface was used as the rest of the letter, the line length would have been shorter, more of an indent. I think it was doctored and to have it match up they would have had to pick a typeface, in this case a condensed one even, to get the line length to match up. I worked for 4 years at a typography house. All before desktop publishing.
Also, the blacked out letters at the bottom - I think are secretary’s initials, meaning it was a dictated letter and it’s blacked out now so no one can see who dictated and then typed it.
