Biden could approach and pay respects, but WAS NOT allowed to 'lay' the wreathe
For comparison, here are past presidents, actually elected and recognized by the US military as their commander in chief. Wreathe is presented for the POTUS to lay, rather than already there to begin with.
Here's Trump
And Obama
And Bush
And Clinton
And Reagan
Only Biden was denied the laying. Could approach and pay respects, but not lay it. Aligns with being a foreign dignitary rather than the POTUS.
Glad you did watch it though, I had to have the sound off to get through it. And because of it, I missed things that others found. Thankfully over overwatches overlap. They are going to regret thinking they could treat these serious matters like a theatre game.
Yea I muted too. It was hard to watch
