I doubt we will get any information about what is discussed, but I bet this visit is critical to the fight against the deep state. There are a lot of corrupt Saudis who were rounded up months ago, and their dealings with American politicians should be shared with us. I hope MbS is bringing a big thumb drive for the president.
It would be nice to outsource the executions of the traitors to the Saudis -- a wood block and a scimitar, job done.
