In recent days, reports have indicated that a growing number of U.S. congressmen and women is expected to pass a resolution which will end U.S. involvement in Yemen's civil war. This resolution would represent a direct challenge to President Trump, who would then have to consider using a presidential veto. While Trump's Middle East strategy may lack clarity, it is undeniable that both MBS and MBZ are pivotal to his influence in the region.

The hostility between Republicans and Democrats in the U.S. Congress has been particularly intense under the current president. The ongoing support by the Trump Administration of the Saudi-led military coalition fighting against the Houthi rebels in Yemen has become the latest focal point of this tension. U.S. media sources have indicated that a group within congress is considering reproducing a version of the resolution that passed the Senate 56-41 last month to rebuke the White House and Saudi Arabia following the Khashoggi murder. The U.S. public appears to be largely against the U.S. military cooperation in Yemen, mainly blaming Saudi Arabia, and in particular MBS, for the crisis. The U.S. Congress appears to now be reflecting public opinion.This resolution would put limits on the amount and type of U.S. support in Yemen. Senators, such as Mike Lee, R-Utah, state that the decision to support the coalition, which was taken by President Obama and Trump, has never been voted on and approved by Congress. The support for a new U.S. strategy is wide, as newly elected Democratic House Majority Leader Steny Hoyer announced he would co-sponsor the legislation. Several Republicans also now seem to be behind the new approach.
