Donald Trump is once again mocking 16-year-old Swedish climate activist Greta Thunberg, this time accusing her of having an “anger management problem.”

Thunberg on Wednesday morning was named Time’s 2019 person of the year, prompting Trump to, nearly 24 hours later, lash out at the decision as “so ridiculous.”

He also mocked Thunberg by saying she must “work on her anger management problem, then go to a good old fashioned movie with a friend! Chill Greta, Chill!”

So ridiculous. Greta must work on her Anger Management problem, then go to a good old fashioned movie with a friend! Chill Greta, Chill! https://t.co/M8ZtS8okzE

Trump himself was also one of Time’s finalists, having been named person of the year in 2016 and suggesting since that he deserves it again.

Asked last year who should be the 2018 Time person of the year, Trump responded, “I can’t imagine anybody else other than Trump, can you imagine anybody else other than Trump?” Time could.

This comes after Trump also mocked Thunberg, who has Asperger’s syndrome, following her passionate United Nations speech in September, sarcastically writing, “She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!”

It also comes just over a week after first lady Melania Trump’s criticism of an impeachment witness for mentioning 13-year-old Barron Trump’s name during her testimony. “A minor child deserves privacy and should be kept out of politics,” she wrote.

“Asperger’s is difficult for teenagers through under any circumstance,” The New York Times’ Maggie Haberman observed. “Being mocked by the president of the US – whose allies get very angry about what gets said about some children – is its own category.”

Following Trump’s attack, Thunberg’s Twitter bio now reads, “A teenager working on her anger management problem. Currently chilling and watching a good old fashioned movie with a friend.”

Twitter was sickened:

#BeBest, bitch.@FLOTUS, really looking forward to your angry tweet telling your husband not to involve minor children in political arguments. I'm sure it's on the way. #thursdaythoughtshttps://t.co/IY8mHnaowA

If you are close to anyone with a disability, it is chilling to see the most powerful man in the world mocking a disability. Autism is not an "anger management problem." https://t.co/acKa3freHf

Based on the outrage from Republicans after Barron Trump was mentioned last week, we can expect Melania to come to the defense of Greta Thunberg today, right? #BeBest https://t.co/tgrQcmlw4A

Where's your outrage about attacks on minor children now, Melania?

Though, this isn't the first time you've remained silent about your husband's attack on a young girl, is it? #BeBest https://t.co/BlpQVtE1nm
