Trump abruptly announced Thursday that the deal was subject to a new condition: Saudi Arabia would have to join the Abraham Accords.

The agreement gives American companies priority access to nuclear reactors and fuel to Saudi Arabia. It's expected to last decades and be worth billions of dollars.

The Trump administration plans to submit a Saudi nuclear pact to Congress within days, despite concerns over missing safeguards, Reuters reported.

Trump announced that the new "peaceful nuclear cooperation agreement" hinges on the Saudis joining the Abraham Accords.
