Over at the White House now, President Donald Trump and first lady Melania Trump have just welcomed back Saudi Crown Prince Mohammed bin Salman for a formal dinner.
Trump tapped the crown prince on his arm a few times in greeting before his wife shook their guest's hand.
A military band was playing as they walked inside to the East Room dinner.
The prince joined the president in the Oval Office earlier, as part of a controversial state visit.
Trump dismissed criticism of Salman when the 2018 killing of journalist Jamal Khashoggi was raised, saying "things happen".
He said the crown prince "knew nothing about it", and of Khashoggi, said "a lot of people didn't like that gentleman".
The president then lashed out at a reporter who asked the question, calling her "fake news" and chastising her, saying: "You don't have to embarrass our guest by asking him a question like that."
