Harvard is probably thinking they just need to draw the $1 billion extra for another 4 years. Unless, Trump runs for a 3rd time which he has floated. If that happens then I think everyone's just screwed.
With an overbearingly powerful executive like the federal US executive you can come up with so many ways to fuck with companies or institutions like this one beyond not giving them money.
It's very dangerous to assume "oh, this will only last four years". The rights currently being eroded (free speech, habeas corpus and voting rights themselves) are required for free and fair elections. Even if the term of the current Shitstain In Chief ends when it's supposed to, his replacement will be from the same cloth.
I'm sure he's got plans to issue an executive order declaring all of the votes against him null and void because they weren't cast and counted within 4 hours of each other on election day.
