Senior White House adviser Jared Kushner returned home this weekend from an unannounced trip to Saudi Arabia, where the White House said he continued discussions on securing Middle East peace. Kushner was accompanied by Deputy National Security Adviser Dina Powell and Jason Greenblatt, special representative for international negotiations, Politico reports. Kushner traveled commercially last Wednesday but flew separately from Treasury Secretary Steven Mnuchin, who arrived in Riyadh to discuss combating financing to terrorist networks. The White House did not reveal who Kushner met with. News of his trip comes as speculation swirls over who will be the first to face charges in special counsel Robert Mueller’s Russia probe, which is reportedly due to produce its first charges Monday. It also came amid reports Sunday that Maryland’s attorney general is investigating one of the Kushner family’s real estate businesses over claims of abusive debt collection practices and poor conditions.
