US President Donald Trump reportedly asked Prime Minister Benjamin Netanyahu last year whether he seriously cared about making peace with the Palestinians.

According to Axios, the mercurial American president went off script in a phone call between the two leaders. The report said the call came just after the Israeli press reported that the Israeli premier was planning to approve settlement construction projects to satisfy his right-wing base.

“Trump thought Bibi was unnecessarily angering the Palestinians,” the news site reported, citing three sources familiar with the call. “So, in the course of a longer conversation that was mostly friendly and complimentary, he bluntly asked Bibi whether or not he genuinely wants peace.”

The report did not detail Netanyahu’s response to that question.
