"Nobody has told me he is responsible. Nobody has told me he is not responsible," the U.S. leader said. "We have not reached that point ... I would love if he was not responsible.”
After the Saudis' explanation Saturday for Khashoggi's death, Trump at first said it was credible. But numerous U.S. lawmakers, including Trump's Republican colleagues, are calling for sanctions against Riyadh. Turkish investigators say Saudi agents tortured Khashoggi, decapitated him and then dismembered his body.
Trump told the Post that "something will take place" in response to Khashoggi's death, but said the United States should not let the incident disrupt a possible $110 billion weapons sale to Riyadh he announced last year.
“It’s the largest order in history,” Trump said. “To give that up would hurt us far more than it hurts them . Then all they’ll do is go to Russia or go to China. All that’s doing is hurting us.”
But one Trump supporter, Kentucky Senator Rand Paul, told Fox News on Sunday, "I don’t think arms should ever be seen as a jobs program."
Other U.S. lawmakers voiced skepticism of the Saudi explanation for Khashoggi's death.
Senator Bob Corker, chairman of the Senate Foreign Relations Committee, told CNN he believes Mohammed bin Salman was responsible, saying, "Yes, I think he did it."
A Trump critic, California Congressman Adam Schiff, told ABC News, "This ought to be a relationship-altering event for the U.S. and Saudi Arabia, that we ought to suspend military sales, we ought to suspend certain security assistance."
U.S. officials are faced with reconciling the Saudi explanation for Khashoggi's death and Turkey's claim an audio recording exists of Khashoggi's torture and death. Trump denies U.S. officials have heard the audio or read transcripts of it, but the Post quoted sources saying that Central Intelligence Agency officials have listened to the audio. Verification of it would make it difficult to accept the Saudi explanation for Khashoggi's death.
European leaders and the human rights group Amnesty International expressed skepticism about the Saudi explanation.
Britain, Germany and France issued a joint statement condemning the killing of Khashoggi and said there is an "urgent need for clarification of exactly what happened." They said the Saudi explanation for the journalist's death needs to be supported by facts in order to be credible.
Turkish President Recep Tayyip Erdogan said he will announce details of his country's investigation on Tuesday.
European Union foreign policy chief Federica Mogherini said the circumstances around Khashoggi's death are deeply troubling, and called for a thorough, credible and transparent investigation.
Amnesty International called on Saudi Arabia to "immediately produce" Khashoggi's body so an autopsy can be performed.
Amnesty's director of campaigns for the Middle East, Samah Hadid, said a United Nations investigation would be necessary to avoid a "Saudi whitewash" of the circumstances surrounding Khashoggi's death. Hadid said such a cover-up may have been done to preserve Saudi Arabia's international business ties.
