Donald Trump has taken several public swipes at Michelle Obama over the years, with the most recent flare‑up coming during the 2024 campaign when he accused her of being “nasty” to him and said she had made a “big mistake” by criticizing him.

Latest: 2024 “nasty” and “big mistake” comments

In late October 2024, at a rally in Atlanta, Trump told supporters that Michelle Obama had been “very nasty” to him in a recent speech and claimed she had “opened up a little bit of a box.” He suggested she had made a “big mistake” by going after him, and framed himself as someone who had “always tried to be so nice and respectful” toward her, despite his long history of promoting birther conspiracy theories about Barack Obama.

Michelle Obama had just campaigned for Kamala Harris in Michigan, where she called out Trump’s “gross incompetence,” “erratic behavior,” and “obvious mental decline,” and reminded voters he had been found liable for sexual abuse in a civil case and was a convicted felon. Trump’s response played well with his crowd: at one point, some in the audience chanted “Lock her up,” and he briefly paused before telling them, “Be nice,” while still using her as a foil to energize supporters.

How this fits their ongoing feud

Their feud is part of a bigger, long‑running animosity between the Obamas and Trump:

  • Trump spent years pushing the false birther claim that Barack Obama was secretly born in Kenya and therefore an illegitimate president, which Michelle Obama has described as dangerous and racist.
  • Michelle Obama has repeatedly criticized Trump’s character and conduct, including highlighting his “Access Hollywood” comments and warning voters about his temperament and treatment of women.
  • Trump, in turn, has periodically “hit back,” complaining about her criticisms and portraying her as unfair or “nasty” toward him, especially when she steps into the campaign spotlight.

An example from earlier years: during the 2016 race, he also took a shot at Michelle Obama by highlighting past remarks she’d made about Hillary Clinton, using them to argue that Democrats were hypocritical in their attacks on him.

Why this is a trending topic now

The question “what did Trump say about Michelle Obama” is trending again because:

  • His late‑2024 comments came in the middle of a heated campaign environment, with Michelle Obama serving as a high‑profile surrogate against him.
  • Clips of him calling her “nasty” and warning she’d made a “big mistake” circulated widely on news sites and political forums, reigniting debate over how he talks about women—especially a former first lady who remains popular with many voters.
  • The broader feud between Trump and the Obamas has become a recurring storyline in U.S. politics, so every new jab tends to get amplified online.

Key points in one glance

  • He said Michelle Obama was “nasty” to him and had made a “big mistake” by criticizing him.
  • He claimed he had always been respectful of her, despite his prior birther attacks on Barack Obama.
  • Her trigger comments focused on his “gross incompetence,” “erratic behavior,” and “obvious mental decline,” plus his status as a convicted felon and someone found liable for sexual abuse.
  • The clash fits a long pattern of back‑and‑forth between Trump and the Obamas that keeps resurfacing in campaigns and online discourse.

TL;DR: Trump’s most talked‑about recent remarks about Michelle Obama are that she was “nasty” to him and made a “big mistake” by attacking his competence and mental fitness, fueling their already long‑running public feud.
