The President provides six pages of history of the impeachment circus in his inimitable style and, in the process, tears Auntie Nancy a, er, new one. I seriously doubt that she or anyone on her staff got through the first page of it, but as the President says on the last page, "... I write this letter to you for the purpose of history and to put my thoughts on a permanent and indelible record."
I would love to quote excerpts of it, but since it's a PDF I can't copy and paste from it. I do hope you will access the link above and download it to read it. It is worth the time to do so!
If any of you actually believe the president deserves to be impeached, then please explain how it is that the Democrats began impeachment proceedings as soon as he took the Oath of Office, and even began threatening to do so before he was in office. And he has been consistently denied any semblance of due process.
