Law enforcement officials at a Virginia military base are still actively investigating a recent incident involving the Trump campaign at Arlington cemetery, sources say.
The Army has said it considers the matter closed.
"Federal law prohibits campaigns from using the military cemetery for political campaigning or election-related activities."
According to the Army, via the article the case is both closed (as the employee who was attacked has decided to not press charges) and that it is an open (investigation) and so related documents are not available under FOIA.
The trumpers were videoing in an area where that is not permitted, and offered video (not yet released) which exonerated them.
If you or I were to have done what the trumpers did, we'd have been arrested, and probably still be in jail. smh.
