Senate Democrats forced a vote under the War Powers Act aimed at blocking continued U.S. strikes on alleged drug-carrying boats off the coast of Venezuela.

Senate Republicans on Wednesday blocked an effort aimed at preventing continued U.S. strikes on alleged drug-carrying boats off the coast of Venezuela.

Democrats forced a vote on the issue under the War Powers Act. In a 48-51 vote, the effort failed to garner enough support to move forward.

The resolution, led by Sens. Adam Schiff of California and Tim Kaine of Virginia, would have blocked the U.S. military from engaging in hostilities with “any non-state organization engaged in the promotion, trafficking, and distribution of illegal drugs and other related activities” without congressional authorization.
