May 22 (UPI) -- The United States placed a $14 billion arms sale to Taiwan on hold to make sure the U.S. military has sufficient munitions stocks for the war with Iran.

Acting Navy Secretary Hung Cao told a U.S. Senate Appropriations defense subcommittee hearing Thursday that the pause was a precautionary measure and that the military still had "plenty" of missiles and interceptors.

"Right now we're doing a pause in order to make sure we have the munitions we need for Epic Fury -- which we have plenty. We're just making sure we have everything, but then the foreign military sales will continue when the administration deems necessary," he said, responding to a progress update query from the chairman of the panel, Sen. Mitch McConnell, R-Ky.

McConnell expressed concern when Cao said the final determination on the sale would be made by Defense Secretary Pete Hegseth and Secretary of State Marco Rubio.
