The Republican-controlled Senate voted on Thursday to end American military
support for a Riyadh-led war in Yemen, and separately held Crown Prince Mohammed
bin Salman responsible for Khashoggi’s killing.
The largely symbolic vote dealt a fresh warning to President Donald Trump, who has staunchly backed the Saudi regime in the face of intense global outrage.
"The kingdom condemns the latest position of the US Senate that was based on unsubstantiated allegations and rejects the blatant interference in its internal affairs,” the foreign ministry said in a statement released by the official Saudi Press Agency.
On the Yemen measure, which more broadly attacks the president’s prerogative to launch military action, 49 Democrats or their allies voted in favor, along with seven Republicans, while another three Republicans abstained.
The Senate also approved a resolution condemning Khashoggi’s murder and calling Crown Prince Mohammed bin Salman, Saudi Arabia’s de facto ruler, "responsible” for it.
The Saudi ministry warned that the kingdom would not tolerate any "disrespect” of its rulers.
"This position by the US Senate sends the wrong messages to all those who want to cause a rift in Saudi-US relationship,” the ministry said.
"The kingdom hopes that it is not drawn into domestic political debates in the US to avoid any… significant negative impact on this important strategic relationship.”
