People can disagree on whether or not Donald Trump should be removed from office. That is our right. But there can be no disagreement about the facts.
Trump would be, technically, the third president to be impeached, following Andrew Johnson — among other things for his removal of Secretary of War Edwin Stanton — and Bill Clinton (for having sexual relations with that woman and then lying about it under oath). Obviously Nixon was on his way but chose to flee the scene rather than undergo trial. Of those impeached, none have been removed from office.
