The Trump administration has submitted a nuclear cooperation agreement with Saudi Arabia to Congress for review. The 30-year accord would allow Riyadh to enrich its own fuel for nuclear reactors, deepening U.S.-Saudi ties amid tensions with Iran. The agreement grants U.S. companies a central role in developing Saudi civilian nuclear infrastructure while largely excluding foreign competitors.

Formally submitted under Section 123 of the Atomic Energy Act, the deal enters a 90-day congressional review period. Unless Congress passes a joint resolution rejecting the agreement, it can take effect without an affirmative vote. The transmission was first reported by The Wall Street Journal.

Democratic lawmakers, including Senators Edward J. Markey and Jeff Merkley and Representatives John Garamendi and Donald S. Beyer Jr., have opposed the deal, arguing it could spark a Middle East nuclear arms race.

They contend the agreement should require Saudi Arabia to forgo weapons-grade uranium production and accept stringent International Atomic Energy Agency inspection standards. Energy Secretary Chris Wright and Saudi energy minister Prince Abdulaziz bin Salman signed the agreement last month as part of a broader civilian nuclear cooperation package.
