This is a fascinating tweet on many levels.
1) I think it's safe to assume that Joe Biden has no SEO expertise, which means that someone with the power to send the President of the United States out for a photo op does. They went out and found someone named Brandon for Biden to pose for a photo op with.
2) To me it's terrifying that Presidential actions are now being dictated by SEO concerns, but it is interesting.
3) I would have expected this kind of thing from Trump, since he was obsessed with his public image. But apparently Biden, or at least someone close to him, is similarly obsessed.
4) Reading between the lines, the fact they responded in this way makes it appear that the administration is becoming concerned with the the growing anti-Biden sentiment that has arisen in the wake of the Afghanistan debacle and issues with cognitive decline that are becoming increasingly harder to hide. That town hall was a disaster [1].
