The House of Representatives narrowly approved a $1.15 trillion National Defense Authorization Act (NDAA) on Wednesday, advancing the annual defense policy bill as lawmakers continue debating U.S. military involvement in the war with Iran. The measure passed largely along party lines by a vote of 216-212 and authorizes funding for military operations, weapons procurement, troop pay raises and national security programs. The legislation also includes provisions strengthening defense cooperation between the United States and Israel while supporting broader efforts to modernize the U.S. armed forces.

The vote exposed deep divisions in Congress over defense spending and the administration's handling of the conflict with Iran. Many Democrats opposed the measure, arguing Congress should not approve increased military funding without greater oversight of the war and questioning the administration's strategy. Republicans defended the bill as necessary to maintain military readiness and respond to growing security threats, including challenges posed by Iran, China and other geopolitical rivals.
