The move by the House Armed Services Committee injects another partisan wedge issue into an already fraught defense bill.

President Donald Trump’s push to rebrand the Pentagon as the Department of War won a victory late on Thursday when Republicans on a key committee voted to make the change permanent.

The House Armed Services Committee narrowly voted along party lines to codify the renaming of the Department of Defense, which Trump kicked off last fall, during marathon deliberations on its annual defense policy bill.

The surprising show of total unity from defense hawks injects another contentious partisan issue into the must-pass defense bill as Republican leaders aim to muscle the $1 trillion bill through the House later this month amid the war against Iran.
