Biden has plenty of other opportunities to take the cocaine that he doesn't need to hide it in a cubbyhole in the White House Library (or wherever else it was).
So who DOES need to slip away every now and then for a coke fix?
I'm going with a key White House aide whom the administration considers to be key to the success of the Biden administration; someone whom they believe they can't be without, but also someone who's not handling the day-to-day stress of the West Wing too well.
If it were just a run-of-the-mill staffer, that person would have been outed and ousted at the soonest media opportunity. The fact that this hasn't happened says a lot.
The culprit is an administration insider whom the team believes is irreplaceable.
So who can that be?

Perhaps it was not Hunter. But He was seen in the library at around that time and he could be getting away from the new wife so he won’t get caught. I am sure that the new wife has official orders to search Hunters living area for contraband.
