This report has not been confirmed by mainstream sources. It is alleged, according to retired CIA analyst Larry Johnson, that during an emergency
meeting Trump tried to "use the nuclear codes" on Iran and
he was stopped by General Dan Caine. The nuclear football is intended for defensive use, and a military commander might refuse an order they deem illegal or outside of that defensive posture.
According to Johnson "there is seriously something wrong with Trump."
