Secretary of State Rex Tillerson is increasingly alarmed by what he sees as secret talks between Jared Kushner, President Donald Trump’s son-in-law and senior adviser, and Saudi Arabian Crown Prince Mohammed bin Salman — fearful that the discussions could backfire and tip the region into chaos, according to three people familiar with Tillerson’s concerns…

Tillerson believes Kushner hasn’t done enough to share details of the talks with the State Department, according to the people, leaving senior U.S. diplomats in the dark on the full extent of the highly sensitive negotiations.

“The problem is, the senior presidential adviser does not consult with the State Department — and it’s unclear the level of consultation that goes on with the NSC,” one of the people familiar with Tillerson’s concerns said, referring to the National Security Council. “And that’s a problem for both the NSC and the State Department and it’s not something we can easily solve.”
