President Donald Trump does not support the idea of a 45-day ceasefire that would take effect by the next deadline, under which Iran would face a major attack on civilian infrastructure if it does not reopen the Strait of Hormuz, a White House official told CNBC on Monday.
The memo from the official, who spoke on condition of anonymity, was released hours before President Trump was scheduled to lead a news conference at the White House.
In a profanity-laced social media threat on Sunday, President Trump warned that the United States would launch attacks on Iranian bridges and power plants unless the Iranian government agreed to “open the F—— Strait” by Tuesday night.
A proposed 45-day ceasefire that could end the five-week war is being discussed by the United States, Iran and a group of regional mediators, Axios first reported Sunday evening, citing sources familiar with the talks.
But a White House official told CNBC on condition of anonymity Monday morning that “this is one of many ideas that (President Trump) has not approved.”
“Operation Epic Fury continues,” the official said, adding that Trump “will speak further at 1 p.m. Eastern time.”
President Trump’s bellicose Truth in Society threat that Tuesday would “bring Power Plant Day and Bridge Day together” implicitly extended a previously imposed 10-day moratorium on attacks that was set to expire Monday.
In a separate post Sunday night, President Trump said the new deadline is Tuesday at 8 p.m. ET.
