The crown prince and Saudi Arabia are under intense scrutiny from lawmakers on Capitol Hill following the killing of U.S.-based journalist Jamal Khashoggi.

Khashoggi was killed after entering the Saudi Consulate in Istanbul on Oct. 2. He had been an outspoken critic of Saudi leadership as an opinion writer for The Washington Post.

Riyadh has made efforts to distance the crown prince from the murder in the wake of news reports that the CIA concluded that Khashoggi was murdered on his orders.

While many world leaders have also condemned the crown prince over Khashoggi’s murder, Putin has not.

"We do not know what happened in reality. So why should we undertake any steps to deteriorate our relations with Saudi Arabia?" Putin said in reference to Khashoggi’s death last month, according to The Financial Times.

Trump has also been reluctant to point the finger of blame at the crown prince, saying the Saudi leader has denied any involvement in the journalist's murder.
