Which of these so called "leaders" will speak up?

It's coming out that The House of Saud is reponsible for the murder of journalist and Washington Post columnist Jamal Khashoggi.

The Washington Post has also reported, based on U.S. intelligence intercepts, the crown prince had directly ordered an operation to lure Khashoggi back to Saudi Arabia.

According to ALI AL-AHMED (Saudi dissident and founder and director of the Institute for Gulf Affairs) during an interview on Democracy Now

"..but the kill team here was connected to Mohammed bin Salman, because two of his bodyguards are part of that team that killed, and one of them actually is the person who cut up the body. There are two of them who did the cutting. One of them is MBS’s own bodyguard."

He's basing these statements on recordings that the Turkish made inside the Saudi Embassy.

So today Trump is Tweeting that he's talked to MBS and he said there no Saudi involvement in this. I guess he'll just take his word for it, kinda like Putin with the whole election thing.

So my question is: Who among these American "leaders" below will speak up?

Or is it not financially optimal?
