The hugely influential Saudi prince is visiting Egypt, Britain and the United States as part of a long foreign trip, his first as crown prince.
He has a close relationship with Trump and his son-in-law aide Jared Kushner, who is seen as having given the green light for Prince Mohammed's rush to consolidate power in recent months.
Critics have labelled the crown prince's campaign a shakedown and power grab, although authorities insist the purge targeted endemic corruption as the country prepares for a post-oil era.
According to a New York Times investigation published yesterday, prominent Saudis held as part of the crackdown were subjected to coercion and physical abuse -- allegations rejected by the Saudi government as "completely untrue."
The crown prince has wooed the West by promising a more open society, one which allows women to drive and relaxes rules on music.
