This is straight reporting from The Hill: the Pentagon canceled a scheduled Tuesday morning press briefing with Defense Secretary Hegseth and Joint Chiefs Chair Gen. Caine, occurring about 12 hours before Trump's deadline for Iran to reopen the Strait of Hormuz or face strikes. No reason was given for the cancellation. The article is well-sourced and the cancellation is confirmed across multiple outlets, though without explanation it leaves open questions about whether this was tactical communication management tied to the Iran deadline.
