Saudi Arabia's powerful crown prince is taking a landmark US tour, meeting with with stars from Elon Musk and Bill Gates to Oprah

Trump has now met with MbS multiple times, both in the US and Saudi Arabia. He has emerged as a strong supporter of the young crown prince, as well as his father, King Salman.

The president brought several charts with him when he met with MbS at the White House that showed the type of weapons, vehicles, and equipment being bought by Saudi Arabia. The deals are worth tens of billions of dollars.

Nader Hashemi, the director of the Centre for Middle East Studies at the University of Denver's Josef Kor bel School of International Studies, told The Independent that MbS' meeting with Oprah may help create a better PR image for Saudi Arabia.

"Saudi Arabia has always had a public image problem in the West because of the obvious things like women’s rights and beheadings," Hashemi said. 

"When you meet with Oprah, even if you're not going to be interviewed, you're seeking the approval of an opinion maker. You're going into people's homes and reaching deep into American culture."

Secretary of Defense Jim Mattis was known for being a hawk toward Iran when he served as a general in the Marine Corps. Though he has argued in favor of keeping the Iran deal intact, he is still wary of Saudi Arabia's Middle East rival.

MbS also serves as Saudi Arabia's Minister of Defense, and has made confronting Iran a top priority for Saudi Arabia. A meeting with his US counterpart is a no-brainer.

Blackstone unveiled a $40 billion infrastructure fund with Saudi Arabia in May 2017 that will "primarily invest in the United States." Saudi funding will account for half of the fund, at $20 billion. 

During this trip, Schwarzman organized an event in New York City where MbS met with 40 US executives.

Friedman wrote a glowing profile of MbS for the Times in November 2017, describing the Saudi crown prince as "a young leader who is driving religious and economic reform, who talks the language of high tech, and whose biggest sin may be that he wants to go too fast."

MbS and Friedman are reportedly supposed to have dinner together at some point during his trip.
