WASHINGTON, March 16 (Xinhua) -- U.S. President Donald Trump on Monday said Israel "would never" use a nuclear weapon on Iran.

"Israel wouldn't do that. Israel would never do that," Trump told reporters at a press conference.

David Sacks, the so-called White House AI czar appointed by Trump, reportedly said on the podcast All-In last week that he was concerned about the possibility of Israel escalating the ongoing U.S.-Israeli war with Iran by using a nuclear weapon.

"Israel could get seriously destroyed," Sacks said on the podcast. "And then you have to worry about Israel escalating the war by contemplating using a nuclear weapon, which would truly be catastrophic."

Trump said Sacks had not shared that assessment with him. ■
