Twitter users are calling out Ivanka Trump over a huge blunder she recently made on social media. On Nov. 21, the U.S. presidential daughter and White House senior staffer cited am 1835 quote and mistakenly attributed it to French historian and political writer Alexis de Tocqueville.

Last week, the House Intelligence Committee held back-to-back public impeachment hearings as part of the ongoing impeachment inquiry against U.S. President Donald Trump. With Trump on the brink of losing his position, his camp is now claiming that the ongoing inquiry is merely an attempt of the Democrats to weaponize politics.

After White House press secretary Stephanie Grisham took a swipe on the impeachment, Ivanka Trump took to Twitter to express her support. Responding to the ongoing impeachment hearings, she insinuated that the Democrats are taking advantage of the power of impeachment to oust her father from office.

“A decline of public morals in the United States will probably be marked by the abuse of the power of impeachment as a means of crushing political adversaries or ejecting them from office,” Ivanka wrote, quoting Alexis de Tocqueville.

Her tweet immediately sparked a Twitter storm, as historians pointed out that the quote was not from de Tocqueville but author John Innes Clark Hare. “I can’t seem to find this quote in either volume of Democracy in America (1835 and 1840). Am I missing something?” commented Twitter user Peter A. Shulman.

Another Twitter user who goes by the name Keepapitchinin pointed out that the quote was from an 1889 book by Hare titled “American Constitutional Law.” “I find the exact statement in an 1889 book, but as a paraphrase of De Tocqueville, not pretending to be his exact words,” she wrote. It turned out that the quote was actually from Hare, who only paraphrased de Tocqueville in his work.

Ivanka Trump has yet to edit or take down her tweet. Five days since her controversial post, Twitter users are still calling her out big time to do some fact-checking before posting inaccurate information on social media.
