The bad data fed to Trump is not his fault. I also agree with The Saker that the truth in Trump's letter is its characterization of the impeachment.

The Saker asks if the presstitutes published Trump's letter. The New York Times did but only by taking exception to every line of it. https://www.nytimes.com/interactive/2019/12/17/us/politics/trump-pelosi-letter.html

The Hill did not post the letter. Presstitute Bob Lehrman kept the content from The Hill's readers and dismissed Trump's letter "as a rich compendium of fallacies" that he will assign to his students so that as future speechwriters they will avoid repeating them. https://thehill.com/opinion/white-house/475532-trumps-letter-to-pelosi-not-unhinged-but-worse-from-a-speechwriters

The Washington Post presstitute Jennifer Rubin finds Trump's letter "bizarre and frightening." But she doesn't provide a copy that would let readers judge for themselves. https://www.washingtonpost.com/opinions/2019/12/17/so-many-hysterical-men/
