U.S. Congress passes Yemen War Powers Resolution; Trump vetoes it

In 2019 the U.S. Congress, for the first time in the history of the 1973 War Powers Resolution, passed a joint resolution (S.J.Res.7) directing the removal of U.S. forces from hostilities in Yemen's Saudi-led coalition campaign that had not been authorized by Congress. In the causal graph this event weakens Armed-Conflict Intensity, a driver that strengthens Global deaths from organized violence (UCDP) — an improving welfare path.

In 2019 the U.S. Congress, for the first time in the history of the 1973 War Powers Resolution, passed a joint resolution (S.J.Res.7) directing the removal of U.S. forces from hostilities in Yemen's Saudi-led coalition campaign that had not been authorized by Congress. The Senate passed it on 13 March 2019 and the House on 4 April 2019 (247-175). President Donald Trump vetoed the measure on 16 April 2019, and a Senate override attempt fell short on 2 May 2019 (53-45). The resolution was led in the Senate by Bernie Sanders, Chris Murphy and Mike Lee, with Representative Ro Khanna leading in the House.
