I have recreated the letter, here is what it could look like if formatted with more love and care in the same font, namely Times New Roman:
As you can already see above same font, but the letter alreay has tons more of character.
And here is what it could look like using a different font, namely Bookman Old Style, giving it a more interesting look:
Both are for sure not yet perfect (and please excuse the typos), but aside that still much better looking than what Trump's intern has produced. The differences are manyfold, but I guess visible enough.

As a work of design, it’s hard to complain about Times New Roman. It was created for a newspaper, so it’s a bit narrower than most text fonts—especially the bold style. (Newspapers prefer narrow fonts because they fit more text per line.) The italic is mediocre. But those aren’t fatal flaws. Times New Roman is a workhorse font that’s been successful for a reason.
Yet it’s an open question whether its longevity is attributable to its quality or merely to its ubiquity. Helvetica still inspires enough affection to have been the subject of a 2007 documentary feature. Times New Roman, meanwhile, has not attracted similar acts of homage.
Why not? Fame has a dark side. When Times New Roman appears in a book, document, or advertisement, it connotes apathy. It says, “I submitted to the font of least resistance.” Times New Roman is not a font choice so much as the absence of a font choice, like the blackness of deep space is not a color. To look at Times New Roman is to gaze into the void.
If you have a choice about using Times New Roman, please stop. Use something else.
