In a rare break with President Donald Trump, the Senate voted on Wednesday to move ahead with a resolution to end U.S. military support for the Saudi Arabian-led coalition in the war in Yemen and lawmakers vowed to push for sanctions against the kingdom in the new year.

Eleven of Trump's fellow Republicans joined Democrats to provide the 60 votes needed to advance the war powers resolution in the Republican-led chamber. The vote paved the way for debate and a vote on U.S. involvement in a conflict that has led to the deaths of tens of thousands of civilians, many of them young children and left millions more at risk of starvation and death by disease.

The nearly unprecedented break the 11 Republicans made from Trump was largely symbolic because the House of Representatives is not expected to take the matter up this year. Trump has threatened a veto.

But backers of the resolution said it sent an important message that lawmakers are unhappy with the humanitarian disaster in Yemen, and angry about the lack of a strong U.S. response to the killing of journalist Jamal Khashoggi at a Saudi consulate in Turkey.

Republican and Democratic lawmakers also vowed to keep pushing after the new Congress take office in January for further tough action against Saudi Arabia, including legislation to impose human rights sanctions and opposition to weapons sales.

"If you want to buy our weapons, there are certain things you have to accept. How you use them matters," Republican Senator Lindsey Graham told a news conference.

"The individual, the crown prince, is so toxic, so tainted, so flawed, that I can't ever see myself doing business with Saudi Arabia unless there's a change there," said Graham, generally a close Trump ally in the Senate.
