The Associated Press gets one good tidbit in a write-up of how President Trump's Saudi Arabian hosts are preparing for his visit:
In Saudi Arabia, people with knowledge of the planning for Trump's trip say the caterers are planning to offer the president steak and ketchup alongside the lamb and hefty portions of rice on the menu. All the meat will have been butchered in a Shariah-compliant halal manner as per Islamic custom.
Why it matters: Trump is notoriously averse to long trips. During the campaign he regularly flew home to New York each night. The AP cites a "worldwide effort to accommodate America's homebody president" that included his aides spending "weeks trying to build daily downtime into his otherwise jam-packed schedule."
