US President Donald Trump welcomed Crown Prince Mohammed bin Salman, often referred to as MBS, the controversial de facto ruler of oil-rich Saudi Arabia, to the White House on Tuesday.

Trump gave the Saudi prince treatment normally reserved for heads of state, welcoming MBS on the South Lawn of the White House amid cannon fire and a military jet fly-over. 

In comments delivered in the Oval Office shortly after his arrival, the crown prince announced that he would increase what was supposed to be a $600 billion (€518 billion) investment in the US to $1 trillion

The visit is the prince's first since the grisly 2018 killing of Washington Post journalist Jamal Khashoggi at the hands of Saudi agents that US intelligence services concluded were very likely operating on the crown prince's orders.
