The president is said to have raised the idea of bombing hurricanes with senior Homeland Security and national security officials on numerous occasions, dating back as far as 2017.
The source said the briefer was “knocked back on his heels” as Mr Trump went on to suggest dropping a nuclear bomb in the eye of an off-shore hurricane would disrupt its formation.
“People were astonished,” the source added. “After the meeting ended, we thought, ‘What the f***? What do we do with this?’”
