President Trump was greeted by Saudi Crown Prince Mohammed bin Salman as he landed in Riyadh today, the first stop on a tour of Gulf states that will also take him to Qatar and the United Arab Emirates. Trump is expected to discuss Iran’s nuclear program, oil prices and Gaza. He’s also expected to focus on securing major investments with the three countries, which Trump claims could reach $1 trillion. This includes a reported arms deal with Saudi Arabia for more than $100 billion. Dozens of business leaders are in Riyadh for Trump’s visit. Among them are billionaire CEOs Elon Musk, OpenAI’s Sam Altman, BlackRock’s Larry Fink and Palantir’s Alex Karp.

Ahead of Trump’s first major overseas trip, over 800 U.S. health workers called on Trump to demand a new ceasefire in Gaza and immediately allow aid to enter the Gaza Strip. The medical workers highlighted the increased risks to children, pregnant women, sick and older Palestinians, who they say are “marching in an agonizing and cruel fashion toward death.”
