In December 2018, Sanders supported a bill with Senators Chris Murphy and Mike Lee to use the 1973 War Powers Resolution to end U.S. support for the Saudi-led military intervention in Yemen. At first, the Senate did not supported it, but after the assassination of Jamal Khashoggi in October 2018 the bill had bipartisan co-sponsors and the Senate passed the bill by a vote of 56–41 on December 13.
