It is horrific that the killing continues in Yemen, a poor backward country pitted against wealthy Saudi Arabia and its allies, including the U.S. From Caitlin Johnstone at caitlinjohnstone.com:

Bernie Sanders has withdrawn his bill to end US support for the Saudi war on Yemen following reports that the Biden administration was working to tank the resolution, with White House aids reportedly saying they’d recommend the president veto it.
Antiwar’s Dave DeCamp reports:
Sen. Bernie Sanders (I-VT) on Tuesday night withdrew his request to vote on the Yemen War Powers Resolution that would end US support for the Saudi-led war and blockade on Yemen, citing White House opposition to the bill.
Sanders said on the Senate floor that he was informed ahead of the scheduled vote of the administration’s opposition to the legislation, meaning President Biden would veto the resolution. The Intercept reported earlier in the day that The White House was pressuring senators to vote against the bill, and Democrats came out in opposition to Sanders’ resolution earlier on Tuesday, including Sen. Alex Padilla (D-CA).
Sanders’ justification for not holding the vote was that the administration claimed it would work with Congress on ending the war in Yemen. He said the White House wanted to “work with us on crafting language that would be mutually acceptable” and insisted if that didn’t happen, he would resume his efforts to end the war through a resolution.
But even if the White House really wants to engage with Congress on the issue, or if Sanders chooses to reintroduce the resolution, the plan will take time, which Yemenis don’t have. There has been a cessation in violence in Yemen, with no Saudi airstrikes since March, but there has been a recent uptick in fighting on the ground.
