Saudi Arabia's powerful crown prince has called the killing of Jamal Khashoggi a "heinous crime that cannot be justified."

Crown Prince Mohammed bin Salman separately said that the killing of the Washington Post columnist will not "drive a wedge" between the kingdom and Saudi Arabia.

His comments came at the Future Investment Initiative. This year's summit, however, has been overshadowed by the killing Oct. 2 of Khashoggi. Turkish officials say a 15-man Saudi team killed the writer at the Saudi Consulate in Istanbul. A member of Prince Mohammed's entourage was allegedly at the consulate at the time.

One of Khashoggi's colleagues from the Washington Post, Tamer El-Ghobashy, joined Armstrong & Getty for a discussion on the death of the one-time Saudi royal insider.
