The Senate Armed Services Committee voted this week to formally change the Pentagon’s name to the Department of War, moving a significant step closer to solidifying President Donald Trump’s rebrand of the Defense Department as permanent.

The move came during the committee’s closed-door deliberations over its defense policy bill, according to Sen. Tim Kaine (D-Va.), who announced the name change in explaining his vote against the legislation.

“It’s a juvenile move that sadly describes the reality of a president who has abandoned meaningful diplomacy in favor of starting doubtful wars in multiple locations and threatening even more,” he said in a statement.
