New York: The US Ambassador to the United Nations Mike Waltz on Sunday (local time) said that the United States rejected Iran's proposal to reopen the Strait of Hormuz because Tehran sought sanctions relief and access to "billions in frozen assets" before negotiations on its nuclear programme.
"They were asking for everything up front, with a promise that they would then talk," Waltz said on CNN's "State of the Union" when asked what US President Donald Trump objected to.
