If you look carefully, you’ll see that these are two different tweets, even though they’re both from OmarKelly and cover the same material.
But that’s not the problem. The problem is the same that Schuyler is seeing: sometimes, for no apparent reason, there’s a burst of tweets that are identical that flood the timeline - 10 or 12 in a row, not just one or two. They come in rapidly, so the timeline scrolls rapidly. But you actually have to follow the timeline for some period of time before you see it.
