Washington (CNN) Jared Kushner, tasked by his boss and father-in-law, President Donald Trump, with mediating Middle East peace early in the administration, has so far staked a bulk of those efforts on the ascendant Saudi crown prince, Mohammed bin Salman.

And according to a new report, the Saudi prince -- known casually by his initials, MBS -- took advantage of that power.

When Kushner, Trump's senior aide, made an unannounced trip to Riyadh last year, the Intercept -- citing three sources -- reported Wednesday , MBS told confidants after the meeting that Kushner had discussed Saudi leaders who are disloyal to the crown prince.

One person "who talks frequently to confidants of the Saudi and Emirati rulers" told the Intercept that MBS bragged to United Arab Emirates Crown Prince Mohammed bin Zayed that Kushner was "in his pocket."

The Intercept also reported that Kushner's information on Saudi royals not loyal to MBS was contained in the President's Daily Brief, a document presented to the President every morning. Kushner lost his access to the document earlier this year when new security clearance rules were instituted.
