Does a verified report say President Donald Trump tried to "access the nuclear codes" but was blocked by Gen. Dan Caine, as claimed by retired CIA analyst Larry Johnson? No, that's not true: There are no credible or verified reports indicating that such an incident ever occurred. While Johnson said on a podcast that there was a report of this incident, he later said in his blog that there is "no confirmation that the report is verified."
The claim appeared in an article (archived here) published by The Mirror US on Apr. 21, 2026, titled "Trump 'tried to access nuclear codes but was stopped by military chief.'" The opening read:
Retired CIA analyst Larry Johnson claims that during an emergency White House meeting, U.S. President Donald Trump attempted to access the nuclear codes but was allegedly blocked by General Dan Caine

The video
On the Apr. 21, 2026, edition (archived here) of the podcast "Judging Freedom," hosted by former New Jersey Superior Court Judge Andrew Napolitano, Johnson said it was during an emergency meeting on Apr. 18, 2026, that Trump attempted to access the nuclear codes. At the 4:42 mark, he said:
One report coming out of that meeting at the White House is that Trump wanted to use the nuclear codes, and then General Dan Caine stood up and said, "No." He invoked his privilege as the head of the military, so to speak. It was apparently quite a blow-up.

Johnson's blog
During his appearance on "Judging Freedom," Johnson did not label the report he mentioned as unconfirmed. He simply called it a "report." It was a different story a day later, on Apr. 21, 2026, in his blog Sonar21 (archived here). While promoting the video of the show featuring his trending comments, he said:
I have no confirmation that the report is verified, but my comment went viral.
