Is finding Cocaine in the White House a problem?

On Jun 2 there was a report of a strange white substance found in the West Wing. It prompted and immediate evacuation of the WH until it was tested and found to be cocaine.

Rumors floated that it was found in the library (among other places) and then the Press Secretary (KJP) said it was found in an area where people on tours are told to leave their belonging and that there were lots of tours over the weekend. Today it is cleared up that it was actually found in an area outside the Situation Room where staff and their guests are told to leave their belongings…not an area that is open to the general public.

The question is: should this be considered a problem? It seems to point that someone fairly high up in the administration (or a guest that has access to sensitive areas) has a coke problem. I personally think this is a problem.

What are your thoughts? Is it a problem or not? Should the guilty party be found? What should the punishment be? And lastly, if this was during the Trump administration, would your answers be the same?
