White House senior adviser Jared Kushner secretly traveled to Saudi Arabia this week and returned to Washington Saturday, according to a report published Sunday.

The trip to the Middle Eastern country marks the third time President Trump's son-in-law has visited this year.

Kushner flew commercial, and traveled with deputy national security adviser Dina Powell and former Trump lawyer Jason Greenblatt.

"The Senior Advisor to the President, the Deputy National Security Advisor for Strategy, and the Special Representative for International Negotiations recently returned from Saudi Arabia," a White House official told Politico in a statement. "The Senior Advisor has also been in frequent contact with officials from Israel, the Palestinian Authority, Egypt, United Arab Emirates, Jordan and Saudi Arabia."

Treasury Secretary Steven Mnuchin led a group to Riyadh, Saudi Arabia, during the group's trip, though it's not clear whether the two parties crossed paths.

The White House did not share who Kushner met with while in Saudi Arabia, though he has a good relationship with crown prince Mohammad Bin Salman, who is also in his 30s.

Trump has called for a peace deal between Israel and Palestine. Kushner, who is Jewish, has worked to broker an agreement between both parties.

"While these regional talks will play an important role, the President reaffirms that peace between Israelis and Palestinians can only be negotiated directly between the two parties and that the United States will continue working closely with the parties to make progress toward that goal," the statement added.

Kushner arrived back in the states late Saturday, in time for a birthday party in honor of his wife, Ivanka.
