Activist Greta Thunberg on Tuesday went after President Trump over comments in which he said he believed “she has to go to an anger management class.”

On Monday, Trump called Thunberg “a strange person” and “a young, angry person” after Israel intercepted a boat she was on carrying aid for Gaza, which has seen mass infrastructure destruction and death amid Israel’s war versus Hamas.

“I don’t know if it’s real anger. It’s hard to believe, actually, but I saw what happened. She’s certainly different. Anger management, I think she has to go to an anger management class. That’s my primary recommendation for her,” the president said of Thunberg.

After being deported from Israel on Tuesday, Trump’s comments about Thunberg were noted to her at Paris Charles de Gaulle airport.

“I think the world needs a lot of more young angry women to be honest, especially with everything going on right now,” Thunberg said.

In international waters, early Monday, Thunberg and others were taken into Israeli custody while they attempted to bring humanitarian aid to Gaza. 

“The ‘selfie yacht’ of the ‘celebrities’ is safely making its way to the shores of Israel,” the Israel Ministry of Foreign Affairs said previously on X. “The passengers are expected to return to their home countries.”

Trump has a history of clashing with Thunberg, a notable climate activist who has pushed world leaders to take more action to fight against climate change.
