People made a lot more fuss about Obama because, you know, "Barack Hussein Obama", etc. Trump was seen doing it too.
But if those three did, then did earlier presidents, and they just weren't documented? Or weren't made a big deal of when they did?
Instead, claiming that Obama and Trump also violating their public trust makes my observation "slanted" is actively dishonest: I said that W did it first, and W did it first. Period.
HW, not W. And maybe others before; HW is just the first I found a reference to. (Also Clinton.)
So it seems to have happened a lot more than I thought...
