Probably the dumbest thing you will read today.

President Donald Trump not only provoked outrage in referring to Senator Elizabeth Warren as “Pocahontas” at an event honoring Navajo veterans at the White House Monday. He may have further helped build the case for his impeachment: Abuse of Congress once formed part of the case to remove a president.

One of the articles of impeachment against Andrew Johnson, one of only two presidents to be impeached, accused him of using “intemperate, inflammatory and scandalous harangues…and loud threats and bitter menaces…against Congress.”Lib

Trump was swiftly condemned by Warren for using what she described as a “racial slur.” Democratic National Committee Chairman Tom Perez described the term similarly. The White House, however, denied it was a racial slur and instead doubled down on the attack on Warren, claiming that she had lied about her Native American heritage to advance her career, something that Warren has denied.

Trump’s comment does not rise to the level of the accusations against Johnson, a Democrat thrust into battle with a Republican-controlled Congress following the assassination of Abraham Lincoln. While it would not be enough on its own to qualify as a case for impeachment, said Allan Lichtman, a political historian at American University, it could bolster the case against Trump.

“That could be a part of an article of impeachment,” Lichtman, the author of a book on Trump titled The Case for Impeachment, told Newsweek Tuesday. “After all, you could couple that with his very intemperate attacks on the judiciary. Combine that with his attacks on the free press. You could couple all of that together and create a fairly powerful article of impeachment.”
