The incident at Arlington National Cemetery

What you can't see in the picture is the incident that occurred just before. An Arlington employee tried to stop a campaign photographer from going to Sergeant Hoover's grave. The reason for this is that Arlington National Cemetery prohibits political speech at the sacred burial grounds.

According to the New York Times, a scuffle broke out that turned physical when the worker tried to stop the photographer, but he went to the grave and took the photo.

The Trump campaign says yes, there was an Arlington Cemetery employee who had a mental health incident. Arlington officials say an incident report was filed and they are reviewing it.

Meanwhile, a liberal veterans group is accusing Trump of using fallen heroes as props. The Trump campaign says it is prepared to release footage proving there was no physical incident. But the campaign has not released any footage, despite claiming it was simply paying respects to the family of a fallen hero at the invitation of the event.

So both sides are pointing fingers at each other over this thumbs-up photo. But it is clear that Arlington National Cemetery – sacred ground – is now an issue in the presidential election campaign. And next to it stands Governor Spencer Cox.
