The CIA has determined that Saudi Crown Prince Mohammed bin Salman ordered the assassination of journalist Jamal Khashoggi, NBC News reported Friday, citing a person briefed on the CIA's assessment.

The CIA declined NBC News' request for comment Friday night.

The Washington Post, which first reported the CIA findings, said the U.S. intelligence agency has high confidence in its findings. Khashoggi was a resident of the United States from Saudi Arabia, and he was a columnist for the Washington Post.

The Saudi Embassy in Washington denied the reports.

"The claims in this purported assessment are false," the embassy said in a statement. "We have and continue to hear various theories without seeing the primary basis for these speculations."

Meanwhile, U.S. President Donald Trump said on Saturday he would speak with Secretary of State Mike Pompeo and the CIA about Saudi journalist Jamal Khashoggi, who was murdered in the Saudi consulate in Istanbul in October, Bloomberg said on Twitter. This according to a Reuters report.

Khashoggi died after entering the Saudi consulate in Istanbul, Turkey, on Oct. 2. Saudi Arabia has said that Khashoggi died in an altercation at the consulate, but its explanations around the journalist's death have changed more than once.
