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.
It looked way too low to be the shoulders. Especially looking at where he ends the verticle and starts the cross. Who makes the sign of the cross below their rib cage?
Oh I see what you mean. I thought you meant he did the points of the cross out of order. It still looks pretty normal to me though.
