The establishment media knows that it cannot hide Biden from extended public view indefinitely, so it is putting out quasi-plausible explanations for his absence, hoping that it will not have to publicly reckon with his cognitive decline before he dies or resigns.
I did not read every single word but I scanned the entire article searching for even a hint of the fact that Biden has a problem with losing his train of thought or making gaffes. Those reasons would have been in the sub headline and in the first paragraph if Biden were a Republican. Those reasons were nowhere to be found. Sickening Ministry of Truth media.
