House Minority Leader Hakeem Jeffries sought to pass a war powers resolution by "unanimous consent" -- a procedure that bypasses the need to hold a recorded vote, provided no one objects -- but was stopped, as expected, by the Republican majority's presiding officer.

The maneuver, staged during a short procedural session while lawmakers remain out of Washington, was largely symbolic but underscored growing Democratic anger over a conflict that has not been formally authorized by lawmakers.
