U.S. President Donald Trump criticized AI leaders advocating a slowdown in AI-model development through a series of social media posts, as OpenAI, Anthropic and Google joined discussions on AI safety. Separately, Saudi Arabia's critical East-West crude oil pipeline was forced to close after Iran-backed attacks. U.S. Energy Secretary Chris Wright told CNBC the disruption would be brief and last days. The U.S. war with Iran has cost the Pentagon an estimated $38.1 billion through Aug. 1 and could become more expensive with each additional month of fighting, according to the nonpartisan Congressional Budget Office.
