The White House cut off the audio feed, which is on a delay, to protect the President from wider embarrassment. It didn't work.
Woke Twitterati are rushing to the big guy's defense, claiming Biden only told a joke to mask the real top secret plans. Man, remember those good ol' days when deep state operatives who carried over into the Trump administration used to leak all sorts of classified and near classified information to the press and the liberals thought it was great to "expose" him? Circa 2016-2020.
Now top secret plans must stay classified. It's tough to keep up with all the changing rules, but I'm starting to get the hang of it after 8 months.
