U.S. President Donald Trump said he and Israeli Prime Minister Benjamin Netanyahu "discussed a lot of things" during a call on Monday.

"It went very well," he told reporters during an extended question-and-answer session at the White House. He said talks with Iran came up and pointed to Iranian-born Uber CEO Dara Khosrowshahi as potentially being a good negotiator.

Answering a follow-up question, Trump said activist Greta Thunberg should take anger management classes.

Thunberg arrived at a port in Israel on Monday after Israeli forces boarded the Gaza-bound boat she was traveling on with other activists and detained them.

The group was protesting Israel’s military campaign in Gaza.

Asked about Thunberg at the White House, Trump said, “I think she has to go to anger management class. That’s my primary recommendation for her.”

He described the climate activist as a “young, angry person,” but added, “I don’t know if it’s real anger.”
