President Trump leaves for the Middle East today on the first overseas trip of his presidency. Trump’s first stop will be Riyadh, the capital of Saudi Arabia, where he’s expected to announce a $110 billion arms deal. The agreement was brokered by Trump’s son-in-law and senior adviser, Jared Kushner, and Reuters reports it could see as much as $300 billion in weapons sold to the Saudi monarchy over the next decade. The deal comes as the Pentagon continues to support a Saudi-led bombing campaign in Yemen, where years of fighting have decimated the country’s health, water, sewage and sanitation systems. The U.N. says around 19 million of Yemen’s 28 million people need some form of aid, with many of them at risk of famine.
