“... leftist President Joe Biden ..”
WOW !
Not only do pigs fly, they do so supersonically !
Likely fake news.
If the Saudis wanted to move towards nuclear power, for time of oil scarcity, they would reasonably do so via someone who actually has rich uranium supplies, like their OPEC+ partner Russia.
If they wanted that nuclear program to include weapons, the same would remain so, seeking development with a country that actually has rich supplies of uranium. This would serve as deterrent vs Shiite central across the Gulf.
Why would the US be involved at all?
