Representative Thomas Massie forces the House toward a vote on eight articles of impeachment against Defense Secretary Pete Hegseth. Massie argues the administration’s military action against Iran was unauthorized and unlawful, and by using a privileged resolution he compels the chamber to address the measure within two legislative days.

The Congressional Budget Office estimates the U.S. war against Iran has cost about $38 billion so far and could add roughly $3 billion more each month. The new accounting gives lawmakers a clearer measure of the financial burden as debate continues over the scope and legal basis of the conflict.

NATO fighter jets shoot down an unidentified drone after it enters Lithuanian airspace from Belarus early Tuesday.
