Most likely he is bot account and or a twitter employee. But twitter filters all responses, allowing them to prioritize the types of responses you see. Which is why shills and bots constantly rise to top of all comments. It's why in some posts that's all the see even though the entire world's majority supports his comment.  They claim this is to encourage engagement. It's really about consensus cracking. They want you to believe your opinion is in the minority. Of course, almost no one supports them. Only a small fraction of mentally ill people oppose the President. But the amplification provided by their filtering gives the illusion of a great divide. It doesn't exist.
