A couple of questions:
Are these flags displayed from staffs? They don’t appear to be.
Does the pride flag constitute the sort of state/nation/society flag mentioned in the flag code?
I don’t know if this actually violates the flag code.
And for those calling for penalties against Biden, I doubt he would have had much direct input on how the flags are displayed. Even if he did, the flag code is not enforced that I know of, at least not outside the military. I suppose you could argue that as CIC Biden falls under military rules and maybe there flag code violations are prosecuted.
It all could have been avoided by just keeping the US flag higher in the display, of course.
