Teen climate activist Greta Thunberg poked fun at President TrumpDonald TrumpProsecutors focus Trump Organization probe on company's financial officer: report WHO official says it's 'premature' to think pandemic will be over by end of year Romney released from hospital after fall over the weekend MORE’s calls to stop vote counts, using his own words from a 2019 tweet.

“So ridiculous. Donald must work on his Anger Management problem, then go to a good old fashioned movie with a friend! Chill Donald, Chill!” the 17-year-old Swedish activist tweeted, in response to a tweet from the president reading “STOP THE COUNT!”

The tweet was a reference to one the president sent in December 2019 with the same phrasing criticizing Time’s decision to name her “Person of the Year.”

Thunberg has poked fun at the president’s criticisms of her in the past, including briefly changing her Twitter biography to “teen working on her anger management problem” after the president’s tweet.

After Trump sarcastically called her “a very happy young girl looking forward to a bright and wonderful future,” she also temporarily added the description to her bio. She made a similar move when far-right Brazilian president Jair Bolsonaro attacked her as a “brat.”
