The White House convened a late-night meeting of the National Security Council on Sunday as the administration coordinated its response to the opening day of direct military operations involving Iran, with senior officials remaining in the Situation Room through the evening hours.

Briefings included the secretaries of defense and state, the director of national intelligence, the chair of the Joint Chiefs, and senior counterterrorism advisers. Officials familiar with the agenda said the discussions covered force posture across U.S. Central Command, protection of personnel at regional installations, and the parameters of any further military activity.

The Pentagon confirmed that U.S. forces in the broader region had moved to elevated alert. Additional air defense assets and naval units had been repositioned in the preceding days, officials said, and contingency plans for rapid evacuation of non-essential personnel from selected facilities were being reviewed.

Congressional leadership was briefed through the afternoon and evening. Aides described the briefings as procedural rather than substantive on operational details, with statutory notification requirements under the War Powers Resolution among the items discussed by White House counsel.

The State Department issued updated travel advisories for the entire Persian Gulf region and Lebanon, recommending that American citizens depart commercial flights remained available. Consular officials began coordinating with allied embassies on shared evacuation contingencies.

Senior officials emphasized that the administration’s near-term priorities were the protection of American personnel, the preservation of freedom of navigation, and the maintenance of communication channels with allies and partners. Officials declined to discuss specific operational decisions or rules of engagement.

White House communications staff began preparing materials for an address by the president, with officials indicating that public remarks would likely be delivered once the operational picture had stabilized. Press briefings were paused during the evening hours to avoid disclosing details that could affect force protection.

Capitol Hill responses began trickling out late Sunday, with members across both parties calling for fuller briefings and for clarity on the scope and authorization basis of any sustained U.S. role. Hearings before the relevant committees were expected to be scheduled within the coming days.
