U.S. and Saudi officials could be “weeks away” from finalizing the core terms of a deal to normalize diplomatic relations between the Gulf Arab monarchy and Israel, according to America’s top diplomat.

“This would be a game changer,” Secretary of State Antony Blinken told House Appropriations Committee lawmakers on Wednesday. “Those agreements, in principle, are very close to being able to be concluded. Now, of course, we will come to Congress with them when they’re ready to be reviewed. But, we could be really weeks away from being able to conclude them.”
