16-year-old Swedish climate activist and TIME 2019 ‘Person of the Year’ Greta Thunberg responded after Donald Trump attacked her on Twitter.
On Thursday morning, Trump mocked the teenager: “So ridiculous. Greta must work on her Anger Management problem, then go to a good old fashioned movie with a friend! Chill Greta, Chill!”
Thunberg then adopted the attack as her Twitter profile.
