Trump-Saudi lunch with business leaders includes some critics of the president

A lunch at the Saudi royal court in Riyadh gave President Donald Trump, Saudi leaders and numerous business executives an opportunity to rub shoulders Tuesday. 

Saudi Crown Prince Mohammed bin Salman hosted the lunch. 

The lunch was part of Trump's high-stakes tour of the Persian Gulf region, targeting business deals and strategic partnerships with three oil-rich nations — Saudi Arabia, the United Arab Emirates and Qatar.
