In a closed‑door session, President Trump engaged in a lengthy, angry exchange with Senator Bill Cassidy of Louisiana. The confrontation centered on Republicans who voted to limit the president's authority to launch military action against Iran. Lawmakers left the meeting visibly divided, underscoring a growing rift within the party.

The dispute reflects broader concerns about executive reach in foreign conflicts. Critics argue that curbing war powers shields investors from sudden geopolitical spikes that can destabilize energy markets and defense contracts. Supporters claim congressional oversight prevents costly, unapproved engagements that could hurt corporate earnings and fiscal stability.

For markets, the clash signals heightened uncertainty around any imminent U.S. response to Iranian activity. Traders may see increased volatility in oil futures and defense stocks as policymakers negotiate the next steps. Investors should monitor legislative moves closely, as a shift in the balance of power could reshape risk assessments across multiple sectors.
