On Wednesday, a measure is being advanced at the behest of House Speaker Paul Ryan (R-WI) aiming to derail House Continuing Resolution 138, a War Powers Act challenge which would force an end to the US military involvement in the Saudi-led War in Yemen.

Under the War Powers Act, any individual lawmaker is intended to be able to raise the matter of an unauthorized war for debate and a vote on the floor. Efforts to do so have failed, however, as the House leadership has used the Rules Committee to sidestep the issue.

This move to derail the debate is part of the first day of lame-duck House business, and Rep. Ryan and the other leaders seem to be hoping to turn the legal challenge of the war into a partisan issue. Minority Whip Rep. Steny Hoyer (D-MD) accused the Republican leadership of shirking Congressional responsibility.

Rep. Thomas Massie (R-KY), however, is hoping to drum up enough Republican support for the legal challenge to prevent this, arguing that the legality of the Yemen War deserves a full debate and vote in the House.

Those wishing to contact their lawmakers to tell them to vote against the attempt to strip privilege from H. Con. Res. 138 should do so quickly, as the vote is expected on Wednesday. You can do so by calling the Capitol Switchboard at 202-225-3121, or find the phone number for their specific representative here.
