Crown Prince Mohammed told Jared Kushner, Donald Trump's son-in-law, and John Bolton, the president's national security advisor, that Mr Khashoggi was a member of the Muslim Brotherhood, according to the Washington Post.
The attempt to criticize Khashoggi in private, stands in contrast to the Saudi government's later public statements decrying his death as a "terrible mistake" and "terrible tragedy".
"It'll take us probably a handful more weeks before we have enough evidence to actually put those sanctions in place, but I think we'll be able to get there", Pompeo said in an interview with a St. Louis radio station on Thursday.
A Turkish official says he believes Saudi journalist Jamal Khashoggi's body was dissolved in acid or other chemicals after it was mutilated at the Saudi Consulate in Istanbul. Amid souring relations, the USA and United Kingdom. And in the Trump administration, Israeli Prime Minister Benjamin Netanyahu has more influence in a US government than he ever has had before.
Netanyahu addressed the issue while talking to reporters on Friday on a visit to Bulgaria. He echoed, however, the rhetoric of the United States administration, which so far has been reluctant to say or do anything that could upset the Saudi monarchy, likely awaiting the blame to be shifted upon a group of rogue agents and officials who have nothing to do with the House of Saud.
Hatice Cengiz, Khashoggi's fiancee, on Friday pleaded for the remains to be returned for proper burial. Some in Washington are hoping this matter will be forgotten with simple delaying tactics.
Officials in the Trump administration have discussed proposals like urging King Salman, the 82-year-old father of the crown prince, to appoint a strong prime minister or other senior official to help oversee day-to-day governance or foreign policy, according to three officials familiar with the deliberations.

He said Saudi officials have not provided a full explanation for what happened at their consulate in Istanbul on 2 October, the day Khashoggi, a prominent Washington Post columnist and critic of Saudi policies, was last seen.
Saudi Crown Prince Mohammed bin Salman told the USA he considered murdered writer Jamal Khashoggi to be a risky Islamist, media reports say. But because of its deep investment in Prince Mohammed as the main linchpin of the administration's Middle East agenda, the Trump administration concluded it could not feasibly limit his power.
Saudi Arabia has denies the comments were made or that its royal family was involved in the killing, and says it is "determined to find out all the facts". "It's been exactly one month since we lost Jamal", said Cengiz. "As a result of our efforts, the world has learned that Khashoggi was killed in cold blood by a death squad, and it has been established that his murder was premeditated", Erdogan wrote in The Post.

"As responsible members of the global community, we must reveal the identities of the puppetmasters behind Khashoggi's killing", he wrote.
USA activists have launched a petition, calling for a section of road near the Saudi embassy in Washington to be renamed Jamal Khashoggi Way.
Some of those implicated in the killing are close to the prince.
