Oil barely garnered a mention from U.S. President Donald Trump during his glitzy visit to Saudi Arabia this week. But the black gold may explain why the trip went so smoothly.

Videos of President Donald Trump at a meeting in Saudi Arabia appear to suggest that he fell asleep, though his eyes were only closed for a few seconds. Trump arrived in Riyadh, Saudi Arabia on Tuesday after a 15-hour flight for a four-day tour of the Middle East.

Trump said during his trip to Saudi Arabia he wants the Gulf kingdom to join the Abraham Accords and normalize diplomatic relations with Israel.

Amazon, Google, and Nvidia are among those who struck deals during Trump's visit to the Middle East, his first major overseas trip of his second term.

He admired the marble in the Qatari palace as “perfecto” and “very hard to buy.” He praised the “gleaming marvels” of the skyline in Saudi Arabia. And he groused about the “much smaller” and “much less impressive” plane that is Air Force One.

(Reuters) -U.S. President Donald Trump, whose family has major business interests in the Gulf countries he is visiting this week, said there was no talk of building a Trump Tower in Syria or golf during his meetings in Saudi Arabia that ended on Wednesday.

The US president gets a "lavender-carpet" reception on a whirlwind visit of Gulf countries mainly focused on shoring up investment.

Although Trump recently attended the funeral of Pope Francis in Rome, Saudi Arabia was originally intended to be his initial overseas destination, just like in his first term. It served as a gilded debut for a foreign policy focused on securing cash infusions for American businesses.
