A bipartisan pair of senators want to make American support for Saudi Arabia, a longstanding ally of the U.S. in the Middle East, more “conditional” on Saudi behavior.

“I would absolutely argue that we should be sending messages to the Saudis that our support for them is conditional,” Sen. Chris Murphy, D-Conn., said Monday at the Center for the National Interest. “I do think it’s time to question whether this alliance is as clear and as solid as many of us may have been told that it was.”
