But the debate could become a virtual trial over Prince Mohammed's responsibility for Khashoggi's murder at the Saudi consulate in Istanbul and Trump's effort to downplay it. Senators could add amendments to further punish the kingdom. Lindsey Graham, R-S.C.; Dianne Feinstein, D-Calif.; Marco Rubio, R-Fla.; Ed Markey, D-Mass.; Todd Young, R-Ind.; and Chris Coons, D-Del.
The killing of Khashoggi, a Washington Post columnist and a critic of Crown Prince Muhammad Bin Salman, at Riyadh's consulate in Istanbul, has strained Saudi Arabia's ties with the West and battered the prince's image overseas.
Khashoggi was killed in October, at Saudi Arabia's consulate in Istanbul. But the Senate could vote to end that arms sale or end USA support of Saudi Arabia's war in Yemen.
Thus, every time the White House tries to put the matter to rest, it only appears to inflame the issue, which is also fueling support for a push to end USA involvement in the war in Yemen.
However, a United States official told NBC that Khalid is not expected to be expelled from the country and would continue on as ambassador.
Graham said he won't support arms sales to Saudi Arabia while Prince Mohammed is in power.
Murphy, D-Conn., on MSNBC's "Morning Joe", said the two officials had been placed "in a bad spot", during the all-senators briefing by President Donald Trump's "maybe he did, maybe he didn't" position on whether Saudi Crown Prince Mohammed bin Salman ordered the murder. "We have to figure out a way to condemn the butchery and the murder in the strongest possible terms without blowing up the Middle East", Kennedy said.
Republican Sen. Richard Shelby said he wouldn't rule out supporting the resolution this time when it comes up for a full vote.
Saudi authorities said the agents who killed Khashoggi exceeded their authority. "You have to be willfully blind not to come to the conclusion that this was orchestrated and organized by people under the command of MBS and that he was intricately involved in the demise of Mr. Khashoggi". Secretary of Defense James Mattis was emphatic last week, telling reporters, "We have no smoking gun that the Crown Prince was involved".
"She didn't tell them anything that (Mattis and Pompeo didn't say)", the Texas Republican said, "so any senator who wants the information has had access to it". Bernie Sanders' (I-Vt.) resolution to end US military support for the Saudi kingdom's assault on Yemen.
The Senate is planning to vote on a proposal to end United States military support to the Saudi-led coalition fighting in Yemen, after members of both parties advanced the resolution last week. Obviously that's a huge sign of progress, but an even more important takeaway is the fact that these senators say they feel purposefully mislead by a Republican administration, and have made a vote against its interests.
Graham is one of the sponsors of the non-binding resolution.
