Here's an interesting tidbit: the latest move by Twitter to deal with a tweet related to President Trump is that it pulled down a Trump campaign video that was presented as a "tribute" to George Floyd, the Minneapolis man murdered by police last week, and whose senseless death has brought so many thousands to the streets across the US. The video remains on YouTube for the moment. It includes a lot of still photos and a few short video clips. It appears that the copyright holder on one (or perhaps more) of those images and clips likely didn't like it to be included for use by a President for a propaganda video they disagreed with, and filed the DMCA claim.

I think there's a very strong fair use argument here for a whole variety of reasons (and, yes, I fully understand the moral claims that whoever took this photo may feel about it being used in this way, but copyright is not supposed to be used in that way).
