On Thursday, Treasury Secretary Steven Mnuchin pulled out of Saudi Arabia’s Future Investment Initiative conference better known as “Davos in the Desert.” It’s a wise decision. As Saudi authorities have yet to come clean about what happened to Saudi journalist and Washington Post columnist Jamal Khashoggi, the U.S. must make clear that the apparent murder and subsequent lies are unacceptable.

Although the conference is only a conference and not broader sanctions or the end of arms deals that some lawmakers have advocated for, it does signal a growing willingness from the Trump administration to consider action against the kingdom.
