The U.S.-Iran conflict enters its fourth day, spreading across the region and pushing oil prices higher. CNBC’s Dan Murphy reports on the latest military developments and what the surge in energy costs could mean for markets. On Capitol Hill, lawmakers prepare to vote on President Trump’s war powers in Iran. Senator Tim Kaine (D-Va.) explains why he opposes the strikes and argues Congress must reassert its authority. And, as AI becomes a tool of modern combat, Christoff & Co. CEO Niki Christoff discusses the Pentagon’s partnerships, Anthropic’s dispute with the Defense Department, and whether meaningful guardrails are possible. Plus, JPMorgan Chase CEO Jamie Dimon addresses President Trump’s $5 billion debanking lawsuit, and OpenAI CEO Sam Altman admits a recent defense deal was rushed.
