U.S. President Donald Trump has sent the U.S. Congress a proposed agreement with Saudi Arabia on civilian nuclear energy while insisting the pact will only go into effect if the kingdom normalizes relations with Israel, a U.S. administration official said?on Tuesday.

The agreement, which was reached in July and would allow U.S. companies to export civilian nuclear technology to the kingdom, was sent to Congress on Monday, according to the U.S. official, who declined to be identified.

The Saudi Embassy in Washington did not immediately respond to a request for comment.
