Greta Thunberg reacted to Donald Trump's comments regarding "anger management issues," offering an ironic reply on Instagram.

After Donald Trump called Greta Thunberg "angry" and "a troublemaker," the Swedish activist responded on Instagram, appreciating his concern for her mental health and suggesting that Trump might have similar issues. Thunberg was recently expelled from Israel after a humanitarian mission, and her reaction comes in the context of older criticisms from Trump, who has mocked her in the past.
