Since 2017, seven authorisations have been granted by the Trump administration to American companies to share sensitive nuclear information with Saudi Arabia.
The Trump administration granted two authorisations to US companies to share sensitive nuclear power information with Saudi Arabia shortly after the killing of journalist Jamal Khashoggi in October, a US senator who saw details of the approvals said on Tuesday.
The timing of the approvals is likely to heap pressure on the administration of US President Donald Trump from lawmakers who have become increasingly critical of US support for Saudi Arabia since Khashoggi was killed in the Saudi consulate in Istanbul in October.
Khashoggi, a native of Saudi Arabia, left in 2017 to become a resident of the United States where he published columns in the Washington Post critical of the kingdom's leadership.
TRT World speaks to Ali Al-Ahmed, the Director of the Institute for Gulf Affairs.
Senator Tim Kaine, a Democrat from Virginia, where Khashoggi lived, called the timing of the approvals "shocking" and adds to a "disturbing pattern of behaviour" of the administration's policy on Saudi Arabia.
The Department of Energy granted the first occasion of the so-called Part 810 authorisation on October 18, 16 days after Khashoggi was killed.
The second occurred on February 18.
US authorities have concluded that responsibility for Khashoggi's death went to the highest levels of the Saudi government.
Riyadh has denied that Crown Prince Mohammed bin Salman was involved.
The authorisations were among seven granted to US companies by Trump's administration since 2017, as Washington and Riyadh negotiate a potential wider agreement to help Saudi Arabia develop its first two nuclear power reactors.
Protecting business interests
The Energy Department has kept the companies involved in the sharing of nuclear technology information with the kingdom confidential, citing the need to protect business interests.
In the past, Part 810 approvals have been made available for the public to view at department headquarters.
The department did not immediately respond to a request for comment about Kaine's statement.
Lawmakers have been anxious to be kept updated about talks on nuclear power development between the administration and Riyadh to make sure any deal contains strict nuclear nonproliferation standards.
Saudi Arabia and Washington had begun talks about nuclear power development before Trump's presidency. But progress has been slow as the kingdom opposes measures that would prevent it from enriching uranium and reprocessing plutonium, two potential pathways to making fissile material for nuclear weapons.
Last year the crown prince said the kingdom did not want to acquire a nuclear bomb, but if its archrival Iran did, "we will follow suit as soon as possible."
Kaine, who had urged the administration to release the authorisations, said the approvals were "one of the many steps the administration is taking that is fueling a dangerous escalation of tension in the region."
Late last month, Trump declared a national emergency because of tensions with Iran and swept aside objections from Congress to complete the sale of more than $8 billion worth of weapons to Saudi Arabia, the United Arab Emirates and Jordan.
Riyadh plans to issue a multibillion-dollar tender in 2020 to build its first two nuclear power reactors, sources said in April. Originally expected last year, the tender has been delayed several times.
The United States, South Korea, Russia, China and France are competing for the business. Reactor builder Westinghouse, which has been hit by a downfall in the US nuclear power industry, would likely sell components to Saudi Arabia in any deal involving US technology. Westinghouse is now owned by Brookfield Asset Management Inc.
