President Trump arrived in Saudi Arabia to begin a four-day Middle East visit that will put the cold calculus of “America First” on full display: Invest great sums of cash into the U.S. economy and get a more engaged Washington in return.

U.S. President Donald Trump touched down in Saudi Arabia on the first stop of four day visit to the region, the first major overseas trip of his second term, with a focus on securing big investments in the United States.

American tech and finance CEOs, including Elon Musk, are also expected to be in Saudi Arabia for a government-hosted conference Trump is scheduled to attend as part of his visit.
