Donald Trump has described the murder of journalist Jamal Khashoggi as one of the "worst cover-ups in the history of cover-ups".
The comments come after Sky sources said body parts belonging to the Washington Post columnist had been found and Turkish president Recep Tayyip Erdogan called Mr Khashoggi's killing a premeditated "murder".
Speaking on Tuesday at the Oval Office, the US leader also said his Turkish counterpart had been "pretty rough" on Saudi Arabia when he addressed the killing in parliament earlier in the day.
President Erdogan demanded Saudi Arabia hold those responsible to account and asked: "Why has the body of someone who was officially said to be killed not been found yet?"
Turkish authorities claim to have an audio recording of Mr Khashoggi's death that supposedly confirms he was tortured, killed, had his fingers cut off and was dismembered. However, Mr Erdogan did not mention it during his address.
When asked if he believed Mr Erdogan, President Trump said he wanted to see the facts first. But he also said consequences for Saudi Arabia would be decided by congress in consultation with himself.
