Donald Trump has vetoed resolutions in Congress to force through a sale of billions of dollars of weapons to Saudi Arabia. Both chambers of Congress voted to prevent the sale over fears the arms will be used on civilians in Yemen. House Speaker Nancy Pelosi issued a furious statement Wednesday evening, saying: “The President’s shameful veto of legislation to block his sale of arms to Saudi Arabia & the UAE tramples over the bipartisan will of the Congress & perpetuates his Administration’s involvement in the horrific, unconscionable conflict in Yemen.” Sen. Tim Kaine, a member of the Senate Armed Services Committee, reacted to Trump’s veto by tweeting: “What. Do. They. Have. On. Him???” Estimates from the Yemen Data Project have put the civilian death toll from the conflict at more than 8,400.
