WASHINGTON — President Donald J. Trump suggested Monday that “rogue killers,” not the Saudi government, might be to blame for the disappearance and suspected murder of Jamal Khashoggi, the Virginia-based Saudi journalist, offering a possible escape hatch to the Saudi royal family as it pushed back against a global furor.

After speaking by phone with Saudi Arabia’s King Salman, Trump said he was sending Secretary of State Mike Pompeo to meet the king in Riyadh to follow up on the macabre case, which has put White House ties to the Saudi rulers in a harsh spotlight and isolated the Saudi government.

CNN subsequently reported that the Saudis were preparing to acknowledge that Khashoggi’s death was the result of an interrogation that went wrong, one that was intended to lead to his abduction from Turkey. There was no independent confirmation.

Trump said Pompeo also might visit Turkey, where Khashoggi was last seen entering the Saudi Consulate in Istanbul on Oct. 2. Turkish media reports, based in part on apparent audio recordings, have said Khashoggi was beaten to death and then dismembered in the building.

Trump said King Salman had denied any knowledge of or involvement in Khashoggi’s fate. The king gave a similar denial to Turkey’s president, Recep Tayyip Erdogan, over the weekend, and Erdogan also suggested that the journalist’s death might not have been officially sanctioned.

The calls appeared to break a two-week impasse over Turkey’s demands to enter the Saudi diplomatic compound. On Monday, Saudi officials met with Turkish police and prosecutors at police headquarters in Istanbul for about two hours, and then began making their way separately to the compound.

Speaking to reporters on the South Lawn, Trump said he had spoken to King Salman for about 20 minutes and “he denies any knowledge of what took place with regards to, as he said, to Saudi Arabia’s citizen. He firmly denies that.”

“We are going to leave nothing uncovered,” Trump said. “With that being said, the king firmly denies any knowledge of it. He didn’t really know, maybe, I don’t want to get into his mind but it sounded to me like maybe it could have been rogue killers. Who knows? We’re going to try to get to the bottom of it very soon but his was a flat denial.”

Asked if he believed the king, Trump said, “His denial to me could not have been stronger that he had no knowledge. And it sounds like he and also the crown prince had no knowledge.”

Khashoggi’s opinion columns in The Washington Post and in Arab media reportedly had antagonized the crown prince, Mohammed bin Salman,who is the de facto ruler of the authoritarian Saudi state. MBS, as he is known, has largely eclipsed the 82-year-old king on the global stage and has built close ties with Jared Kushner, Trump’s son-in-law.

The president’s credulity with the Saudi king is not the first time he has accepted a foreign leader’s version of events that contradicts a consensus on Capitol Hill, among experts on regional politics and in foreign capitals.

Trump memorably dismissed his own intelligence community’s conclusions that Moscow interfered with the 2016 presidential election, accepting Russian President Vladimir V. Putin’s denial of any involvement during a news conference in July in Helsinki. Under intense criticism, he later said he had misspoken.

As criticism intensified over Khashoggi’s disappearance, Trump also has appeared to back down. After days of sidestepping the furor, he told “60 Minutes” in an interview broadcast Sunday that he would impose “severe punishment” if Saudi authorities were found responsible for Khashoggi’s death, without saying what that might be.

His comments prompted pushback from Riyadh, where Saudi officials warned they would respond in kind.
