President Donald Trump has had deep business ties to the Saudi Arabian court for more than two decades.

And those ties have been called into question over his lack of a tough response to Riyadh since journalist Jamal Khashoggi disappeared and was possibly killed at the Saudi consulate in Istanbul.

"Having a President with global business ties means we've got ongoing worries that policy is going to be affected by his business interests," Robert Weissman, president of Public Citizen, which tracks potential conflicts of interest in the Trump administraition, recently told CNN.

"We know that historically the Saudis have spent huge money on Trump properties and we know that since he became a candidate and was elected they have targeted discretionary spending at his hotels," Weissman added.
