From NBC News:
The Senate voted 55 – 44 to block a resolution to end US involvement in Yemen. The resolution was co-sponsored by Sens. Bernie Sanders, I-Vt., Mike Lee, R-Utah, and Chris Murphy, D-Conn.
The measure was an attempt to rein in what its supporters say is unchecked presidential power in the use of military force. It would have forced the immediate withdraw of the U.S. from the area, except for purposes of fighting Al Qaeda, until Congress provides specific authorization.
Sen. Bob Corker, R-Tenn., the chairman of the Senate Foreign Relations Committee, opposed the measure, saying the discussion was “tinged” with politicization because of the timing of the vote. For the first time on a war powers matter, the senators used a provision known as a privileged resolution that allowed them to force the measure despite objections.
Corker announced that his committee would take up a new Authorization of Use of Military Force in his committee on April 19, saying that would be a better way to address congressional authority in war. The U.S. has been using the same war authorization to fight in overseas conflicts since 2001, which was passed in response to the Sept. 11 attacks and has been reauthorized several times since.
Senate Majority Leader Mitch McConnell called the resolution “misguided.”
“Withdrawing U.S. support would increase, not decrease, the risk of civilian casualties. And it would signal that we are not serious about containing Iran or its proxies,” McConnell said on the Senate floor.
