The fiancée of Jamal Khashoggi on Monday criticised President Donald Trump's response to his killing, urging him to set aside US trade interests in the push for truth, and demanded Riyadh disclose more details to bring those who ordered it to justice.
The death of Khashoggi - a Washington Post columnist and a critic of Saudi Arabia's de facto ruler, Crown Prince Mohammed bin Salman - sparked global outrage and pitched the world's top oil exporter into crisis.
Trump has hedged his criticism of Saudi leaders over Khashoggi, insisting he does not want to imperil a "tremendous order" of $110 billion of weapons he says will support 500,000 US jobs - figures that experts say are highly exaggerated.
His fiancée, Hatice Cengiz, told an audience on a visit to London she was disappointed with Trump's approach. "I am disappointed by the actions of the leadership in many countries, particularly in the US," she said.
"President Trump should help reveal the truth and ensure justice be served. He should not pave the way for a cover-up of my fiance's murder. Let's not let money taint our conscience and compromise our values."
However, an internal document seen by Reuters from Lockheed Martin forecasts fewer than 1,000 positions would be created by the defence contractor, which could potentially deliver around $28 billion of goods in the deal.
Lockheed instead predicts the deal could create nearly 10,000 new jobs in Saudi Arabia, while keeping up to 18,000 existing US workers busy if the whole package comes together - an outcome experts say is unlikely.
A person familiar with Raytheon's planning said if the Saudi order were executed it could help to sustain about 10,000 US jobs, but the number of new jobs created would be a small percentage of that figure.
The White House did not immediately respond to a request for comment.
Jobs are important to Trump. He campaigned on his ability to create American jobs, especially high-paying manufacturing ones. Meanwhile he has limited his criticism of Saudi leadership over the killing of a prominent critic because he did not want to endanger the massive arms deal.
Trump's 500,000 figure has been greeted with widespread scepticism given the five biggest US defence contractors, who make nearly every item on the Saudi list, now employ 383,000 people.
Documents seen by Reuters and interviews with defence industry sources familiar with the arms package suggest that between 20,000 and 40,000 current US defence industry workers could be involved in Saudi-bound production if the whole $110 billion package goes through.
Since Trump's trip to the Kingdom last year, little economic activity has taken place beyond Lockheed's work on four frigates the Saudis have ordered.
The order will yield nearly 10,000 jobs in the Saudi ports for maintenance workers, but only 500 new US jobs will be created, according to documents seen by Reuters.
Executives at the several of top US defence companies say Riyadh wants to develop new domestic industry and to create new jobs and local expertise as a part of Crown Prince Mohammed bin Salman's Vision 2030 initiative to wean the country off oil dependency.
Saudi Arabia has set a goal of creating 40,000 defence industry jobs by 2030.
In short, 500,000 jobs Trump keeps bringing up is at least three to five times higher than what one could expect from the Saudi deal, given the estimates from the companies themselves, plus the most generous use of an indirect multiplier.
By its own math, the US State Department said in May 2017 that the Saudi deal could support "tens of thousands of new jobs in the United States."
