According to ABC news, in December 2019 Thunberg was attacked by a sitting US president, Donald Trump, after she was named Time's youngest Person of the Year. Trump tweeted that "[Thunberg] must work on her Anger Management problem, then go to a good old fashioned movie. Chill Greta, Chill!" In response, Thunberg changed her Twitter (now X) profile description to read: a "teenager working on her anger management problem. Currently chilling and watching a good old fashioned movie with a friend."[244]
Also in December 2019, Thunberg was criticized by the German rail firm Deutsche Bahn (DB), after she tweeted a photo of herself on an overcrowded train in Germany, stating she was "finally on my way home" from the COP25 UN climate conference in Madrid. DB initially apologized for the inconvenience but later deleted the tweet and chided Greta for not acknowledging their efforts to provide her with a seat in first class. Greta clarified that she only obtained a seat after four hours into her journey and emphasized that overcrowded trains indicate high demand for train travel. Despite the controversy, fellow passengers reported that DB staff treated Greta kindly, even offering her chocolates typically reserved for first-class passengers.[245]
