The 10th article of impeachment against President Johnson was for abusive rhetoric toward Congress in furtherance of white supremacy.
Article X of the articles of impeachment passed by the House of Representatives against President Andrew Johnson begins as follows.
Seems like a good day to remind folks that one of the articles of impeachment approved against Andrew Johnson was about his rhetoric against Congress.
"did attempt to bring into disgrace, ridicule, hatred, contempt and reproach the Congress of the United States...to impair and destroy the regard and respect of all the good people of the United States for the Congress and legislative power thereof"
