Apparently people don't have a search engine. Hanging lobes being turned into attached lobes happens all the time w/ facial surgery. Especially when the lobes are drooping due to aging and they've had a facelift.
Biden was advised that he needed to look "younger and fresher" and to "sound" more sober and "mature" in order to make him appear to be "presidential". POTUS was calling out his stupid pet tricks. Nothing more. Basically telling the douchebag his reinvention won't work.
Who tipped off POTUS? Oh IDK… Maybe USSS.
